How Shai Gilgeous-Alexander forged his own path to the NBA MVP conversation
A formerly “puny” man could not find anyone tall enough to guard him.
A few years into his professional career, Shai Gilgeous-Alexander needed to add post-up drills to his summer routine. His trainers, far from the typical troop that surrounds an NBA superstar, couldn’t meet the criteria. Gilgeous-Alexander spends his summers in Hamilton, Ontario, near where he grew up. His morning workouts, which begin at 6 a.m., include a Team Canada assistant coach and six friends from high school.
The gang goes by the name of its text chat: “Sunrise Training.” But no regular sunrise trainer is bigger than 6 foot 2. Whatever the crew wanted to try with Gilgeous-Alexander on the low block, it couldn’t come close to replicating the MVP candidate’s NBA counterparts. They were determined to solve the problem.
The gymnasium where he and the sunrise trainers work contains three courts: one he and his friends were using that day, another empty one and one more where a 6-8 stranger, Stefan Borovac, was shooting around. Both he and Gilgeous-Alexander’s group finished around the same time. As Borovac headed to the door, passing the sunrise trainers on the way, Nate Mitchell, Gilgeous-Alexander’s summer coach and a coach with Team Canada for nearly a decade, wandered to this power-forward-sized figure.
“Can I grab you for a second?” Mitchell asked.
The sunrise trainers were about to acquire a new member.
Gilgeous-Alexander, with his unconventional training crew, has become an unconventional megastar. He is the best player on the 50-11 Oklahoma City Thunder, who are running away with the Western Conference’s top seed. He’s tracking to win his first scoring title, averaging 32.6 points and most recently dropping 51 Monday against the Houston Rockets, his fourth 50-point performance over the past seven weeks. With only a quarter of the season remaining, Las Vegas has him as the odds-on favorite to win his first MVP.
The 6-6 guard moves as if he’s beholden to directions on Waze. Sure, he arrives at expected destinations — in the post, from his cushy midrange or (now more than ever) while pulling up from 3-point land — but in his journey there, he will weave onto a dirt path no one else knew existed. He halts just when it seems he’s about to speed up, jolts when a defender succumbs to one of his dekes. That skill has taken him to the forefront of the MVP conversation.
His pacing is unlike anyone else’s. But then again, so is his preparation. And on that morning, before Gilgeous-Alexander had reached even All-Star status, he needed someone to match his skill — or, at least, his size and quirks.
Mitchell pointed to Canada’s greatest active player and explained the situation to Borovac, a former D-I baller at UMass-Lowell who grew up not far away from Gilgeous-Alexander. Mitchell saw Borovac sinking jumpers and dunking, an acceptable test of his athleticism. He asked if Borovac would join the next morning to guard the All-Star in post-up drills.
“I’d be happy to,” Borovac responded.
He returned the next day and fared well. Gilgeous-Alexander scored more often than not, but Borovac was competitive, enough so that the sunrise trainers invited him back the following morning. And the next one. And the next one. And the summer after that. And the subsequent summer, too.
Years later, Borovac remains a member of the team, the guy with a daily summertime task that might make Sisyphus quit. The sunrise trainers use more than just one player to guard Gilgeous-Alexander. His offseason strategy is to face live defenses with moving parts, a situation more replicable to the ones he sees in NBA action, instead of repeating the same drills on a loop. But when it comes to post-ups, Borovac is the brawn in Gilgeous-Alexander’s grill.
“Stef has the hardest job in the world,” Mitchell said.
Gilgeous-Alexander’s usual routine begins at 6 a.m., but this is a public gym, where camps enter some days only an hour later. On those mornings, the sunrise trainers arrive at 5 a.m., just so Gilgeous-Alexander can get his usual routine in before heading to strength training later and then returning to the gym in the afternoon for more shooting.
This is Gilgeous-Alexander’s life — and it has been for a while. Starting in eighth grade, he would arrive at his school’s gym at 6 a.m. daily to get shots up 2 1/2 hours before classes started.
A unique approach has taken him to the pinnacle of basketball. Most high school recruit rankings plopped him somewhere in the 30s before he headed to Kentucky in 2017. He wasn’t drafted until the end of the lottery the next year. The LA Clippers dealt him to the Thunder as part of the Paul George trade after only one pro season, when he showed promise, but when no one predicted he would become one of the NBA’s preeminent franchise centerpieces.
His in-season workouts are more routine than those summertime sessions, going through usual warmups with Oklahoma City’s coaches before games, practices or in open gyms. But the offseason is when Gilgeous-Alexander’s approach stands out, because no one of his level does it like him: with the same group of loyal friends who never sniffed the NBA and with a slew of live defenders at all times hustling until their hearts feel like they’ll give out just to gang up on a slithery scorer.
It’s no wonder that Gilgeous-Alexander’s game doesn’t look like anyone else’s.
“He’s ahead of his time,” Thunder coach Mark Daigneault said in a conversation with The Athletic. “Intuitively, he’s where the scientific research is, which is you wanna be making decisions. You want randomness in your workouts. You want variability. You want interweaving in the workout. He kinda does that naturally.”
And the science doesn’t end there.
From a young age, Gilgeous-Alexander understood he had to compensate for a once-slight frame. He estimates he was only 5-7 at 13 years old, though others who knew him then claim he was 5-6.
“I was puny,” he said in a recent interview with The Athletic. “I was like my mom’s height.”
In a tall man’s game, this presented issues. Gilgeous-Alexander’s first solution? Outwork everybody.
Gilgeous-Alexander’s former club coach, Dwayne Washington, was a teacher at St. Thomas More Catholic Secondary School, the first high school the future star attended. At only 13, he asked a favor of Washington: Could teachers open up the gym at 6 a.m. daily so he could conduct workouts before school?
“I was like, ‘Oh man, nobody ever asked that,’” said Washington, who remembered becoming emotional after receiving the request. “He’s very, very consistent and very disciplined, more than anybody I’ve ever met.”
Washington can’t recall Gilgeous-Alexander taking a morning off — from eighth grade through the end of high school. If he or another teacher were unable to unlock the doors on a particular day, Gilgeous-Alexander would go to the local YMCA instead, arriving there at 5 a.m.
This was just the start.
Washington, a native New Yorker who learned the game from watching local, herky-jerky guards such as Rod Strickland, was not just a basketball coach and physical education teacher; he also taught science. His goal with Gilgeous-Alexander, a bright student obsessed with the game, was to mesh his two areas of expertise.
“I’m a nerd,” Washington said. “That’s what it comes down to.”
The best way for Gilgeous-Alexander to compensate for his size was to fiddle with timing. Washington taught him about acceleration and deceleration, about how slowing down quickly could create as much space as speeding up just as fast.
He compared Gilgeous-Alexander to a car with four gears, telling his student never to rev to fourth gear, where he could too easily lose the wheel.
“You’re never gonna be faster than Allen Iverson,” Washington explained to him. “But what you can do is control your gears.”
He surmised an on-court formula for Gilgeous-Alexander: Go from third gear to first gear, then first gear to third gear, then ease down to second gear and then first again before ratcheting back up to second. Avoid shifts from second to third gear; that would be too predictable. As Washington advised Gilgeous-Alexander, even a rocket can’t throttle where it wants if the opponent knows where it’s going.
“I was always a quick learner,” Gilgeous-Alexander said. “So I always tried to soak things up and just get better as fast as I could and use them instinctually throughout the years.”
Washington directed Gilgeous-Alexander to move diligently enough that he could spin in a new direction, if necessary. His strides would have to remain short, already an elite skill of Gilgeous-Alexander. He’d implore the guard to count in his head as he maneuvered through gears — “one thousand one, one thousand two” — just to master the timing.
That was physics. Next was biology. They worked on breathing techniques.
“Most people wanna go, go, go,” Washington said.
But not Gilgeous-Alexander. Controlled breathing would keep the heart rate down. The calmer the player was, the more composed he could be shifting from third to first gear and back again to third.
Finally, geometry.
Washington believed too many players viewed a basketball court as a canvas for straight lines. A driver starts at point A and wants to dart to point B. But there are more options to consider.
He taught Gilgeous-Alexander about the strength of triangles. If a defender stopped him from fighting to point B, that would be just dandy, as long as Gilgeous-Alexander targeted a point C, too.
“Make them think they beat you to the spot and then you actually go the way you really wanna go,” Washington said. “So, sometimes you use their strength to your advantage. If they’re faster than you, let them be faster than you. If they stop you, let them. They got there first. But you never have to rush.”
Gilgeous-Alexander would bring notebooks to his workouts, writing down each drill Washington taught him, which became a tradition.
“I wasn’t gonna remember on the fly,” Gilgeous-Alexander said.
He jotted down drills from other coaches and began watching trainers and his favorite players on YouTube, taking notes about what he observed, then attempting to replicate them in the gym.
During his free time, he read the notebooks “like it was homework,” Washington remembered.
“What’s unique about him is he’s player-led. He’s not coach-led,” Daigneault said.
Only one man holds the secret to stopping Gilgeous-Alexander, and he won’t share it.
Lu Dort knows the leader of the Thunder well. A fellow Canadian, he began competing against Gilgeous-Alexander when he was 13. They have been teammates in Oklahoma City for six seasons. And Dort, an All-Defense candidate, insists he is the one person who can stop this otherwise untamable scorer. At least, this is what he tells Gilgeous-Alexander regularly, though his strategy will remain inside his brain.
“I can’t go into details like that,” Dort said during a one-on-one conversation when pressed for a hint. “I don’t know who’s gonna read this. … But yeah, he won’t get over his average (against me). I mean that, for real.”
Despite the length of their relationship, Dort didn’t realize the breadth of Gilgeous-Alexander’s basketball knowledge until his rookie year with the Thunder. The two lived together in a five-bedroom home just outside of Oklahoma City in 2019-20, then traveled to the NBA Bubble during the COVID-19 pandemic, when there was not much to do other than play or watch ball.
When they flipped on games, Gilgeous-Alexander would point out nuances on the court. A defender would get caught on his heels, and he would explain what move should follow. Another would help from the weak side, and he would mention the open passing lane and how to exploit it.
Dort’s favorite Gilgeous-Alexander move is the stepback jumper going left, which isn’t new. Gilgeous-Alexander already had that one perfected by the time he got to high school.
Gilgeous-Alexander is Dale Earnhardt, the NBA’s preeminent driver. He blisters to the hoop more than anyone else in the league. The Thunder score 119.8 points per 100 possessions directly off his drives, according to Second Spectrum, second only to Kevin Durant among NBA high-volume drivers.
He twirls defenders out of their shoes when he plants for the stepback special. His speed shows best while he’s slowing down.
“You’ll be watching it and be like, ‘Yeah, my knees can’t do that,” Thunder center Isaiah Hartenstein said.
The midrange stepback going left is another example of Gilgeous-Alexander, a right-handed shooter, doing things his way. When driving this season, he goes left 57 percent of the time. He looks comfortable enough veering that way that some defenses will actually scheme to force him to his strong hand.
This was not always the case.
“I was very right-hand dominant from until I was, like, 9 (years old),” Gilgeous-Alexander said.
Determined to change that, he began to build left-hand coordination. A 9-year-old Gilgeous-Alexander put himself through dribbling drills using only his left hand, layups only with his left and floaters only with his left.
“Sometimes I’d go to the gym and not touch the ball with my right hand,” he said.
By the time he was 12, he had grown more ambidextrous. He had the skill, just not the size.
Gilgeous-Alexander’s first growth spurt arrived from eighth to ninth grade, when he sprouted to 5-10. In 10th grade, he was 6-2. A year later, he reached 6-4, then finally 6-6.
He didn’t stand out on the national circuit until he was large enough for anyone to notice him. He tried out for Team Canada at 14, hoping to land on one of the junior teams, but he got cut. Gilgeous-Alexander fell short in the next two years. Eventually, at 17, he made the senior national team.
“I always thought I was better than I was,” he said.
Now, he keeps good company, the commander of Team Canada, though arguably not the top dog in his family. His mother, Charmaine Gilgeous, was an All-American at Alabama and a two-time Olympian in track and field. She still playfully jabs at her son for making twice as many Olympics as he has.
But she’s never drained a stepback over Jrue Holiday.
In the age of the 3-pointer, to no one’s surprise, Gilgeous-Alexander isn’t operating like other high-volume guards, many of whom chuck up long balls without a filter.
Only about a quarter of his shots come from deep, though he’s added more 3s to his game this season, hitting 37 percent of them. He’s never hoisted this many off the dribble.
He feasts from the short midrange, where he’s nailing more than 50 percent of his attempts, and gets to the basket and free-throw line often. Among players who finish an above-average number of their team’s possessions with a shot, a turnover or a drawn foul, he ranks fourth in the NBA in true-shooting percentage, an all-encompassing metric that accounts for the value of 2-pointers, 3s and free throws. He rarely turns it over, too.
Usually, the more usage increases, the more efficiency goes the other way. That’s not happening in Oklahoma, where Gilgeous-Alexander, ignored through adolescence, has forged his path to join basketball’s elite.
“It’s like LeBron (James) in his prime, Giannis (Antetokounmpo), the speed of (Ja) Morant, the speed and power of (Russell) Westbrook; he’s a great athlete, but he’s not an overpowering athlete, where those guys are,” Daigneault said. “And yet, he gets to the same places on the floor as they do. And to me, that says it all about the skill.”

NBA player calls for Hawks to cancel their ‘Magic City’ strip club promotional night out of respect for women
NEWYou can now listen to Fox News articles!
An NBA player has taken exception to an Atlanta Hawks promotional night, which is a nod to a famed strip club in the city.
The Hawks have “Magic City Night” scheduled for March 16 against the Orlando Magic, but a player for neither team isn’t too fond of paying tribute to a strip club, which has been famed for its late-night stories involving athletes, celebrities and more.
While the Hawks call it an ode to a “cultural institution,” San Antonio Spurs center Luke Kornet shared his displeasure in a letter posted on Medium.

Kornet, a nine-year veteran and 2024 NBA champion with the Boston Celtics, called for the Hawks’ promotional night to be canceled later this month, saying that it is disrespectful to women to honor the strip club.
“In its press release, the Hawks failed to acknowledge that this place is, as the business itself boasts, “Atlanta’s premier strip club.” Given this fact, I would like to respectfully ask that the Atlanta Hawks cancel this promotional night with Magic City,” Kornet wrote in his post.
“The NBA should desire to protect and esteem women, many of whom work diligently every day to make this the best basketball league in the world. We should promote an atmosphere that is protective and respectful of the daughters, wives, sisters, mothers, and partners that we know and love.”
The Hawks boasted about the theme night in its press release, including a live performance by famous Atlanta rapper T.I., a co-branded, limited-edition hoodie and even the establishment’s “World Famous” lemon-pepper chicken wings in the arena.

“This collaboration and theme night is very meaningful to me after all the work that we did to put together ’Magic City: An American Fantasy’,” said Hawks principal owner, filmmaker and actor, Jami Gertz, said in a press release. “The iconic Atlanta institution has made such an incredible impact on our city and its unique culture.”
Kornet wrote that allowing the night to continue “without protest would reflect poorly on us as an NBA community, “specifically in being complicit in the potential objectification and mistreatment of women in our society.”
Kornet wrote that “others throughout the league” were surprised by the Hawks’ decision to have this promotional night.
“We desire to provide an environment where fans of all ages can safely come and enjoy the game of basketball and where we can celebrate the history and culture of communities in good conscience. The celebration of a strip club is not conduct aligned with that vision,” he wrote.

The Hawks have seen good reception for the promotional night, as Tick Pick reported a get-in price was initially $10 for the game and has since skyrocketed to $94.
Kornet is in his first season with the Spurs, his sixth NBA team, where he has played mainly in a bench role. He averages 7.1 points and 6.5 rebounds per game across 50 contests.

Shaikin: Clayton Kershaw’s ‘perfect’ ending has one final chapter in WBC
SCOTTSDALE, Ariz. — How do you improve on the perfect ending?
Clayton Kershaw stood in the desert heat Monday, wearing a far darker shade of blue than the Dodgers do. He does not need a medal, or a chance to fail. His election to the Hall of Fame will be a formality.
In his farewell year, the Dodgers won the World Series, becoming baseball’s first back-to-back champions in 25 years. He secured a critical out. He bathed in adoration at the championship rally, and he told the fans he would be one of them this year.
“I’m going to watch,” he hollered that day, “just like all of you.”
Four months later, he was back in uniform.
He wore a dark blue jersey with red-and-white piping. As Team USA ran through its first World Baseball Classic workout, Kershaw participated in pitchers’ fielding practice and shagged fly balls during batting practice. He could have been home with his five kids, and instead he was rushing off the mound to take a throw at first base.
That November night in Toronto, as it turned out, was not the last time we would see him in uniform.
“Feels good,” he said Monday. “I wouldn’t put on a uniform for anything else. This is a special thing.”
He put the World Baseball Classic into red, white and blue perspective.
“It’s a bucket list thing for me,” he said.
He is either self-deprecating or painfully honest about his capabilities right now, or perhaps a little of both.
The last World Baseball Classic came down to Shohei Ohtani pitching to Mike Trout. This one could come down to Kershaw pitching to Ohtani.
“I think, for our country’s sake, it’s probably better if I don’t,” Kershaw said.

Never say never. Team USA planned to run a tremendous rotation of Tarik Skubal, Paul Skenes, Joe Ryan and Logan Webb, but now Skubal says he will pitch just once in the tournament. Skenes says he’ll pitch twice. Ryan says he won’t pitch in the first round, at least.
Kershaw might be needed beyond the role he was promised: save the team from using the current major league pitchers in blowouts or extra innings.
In 11 career at-bats against Kershaw, Ohtani has no hits. Kershaw won’t duck the assignment if gets it, but he considers it so unlikely he is happy to share his game plan publicly.
“It’s throw it, pitch away, play away, hope he flies out to left,” Kershaw said. “Don’t throw it in his barrel.
“I can’t imagine, if it comes down to USA versus Japan, with the arms that we have, that I’ll be needed. But I’ll be ready.”
Kershaw’s average fastball velocity dropped to 89 mph last season, but he led the majors in winning percentage. He could eat innings for some team — maybe even the Dodgers, with Blake Snell and Gavin Stone all but certain to be unavailable on opening day.

But, even with his success last year and even with the joy of wearing a uniform once again, he insists he isn’t interested in pitching beyond the WBC.
“I don’t want to,” he said. “You can’t end it better than I did last year. I had a great time last year. It was an absolute blast and honor to be on that team. I think that was the perfect way to end it. Honestly, I don’t know if I would have enough in the tank to pitch for a full season again. I’m really at peace with that decision.
“This is kind of a weird one-off thing, but you can’t really turn down this opportunity. It wasn’t easy to get ready for this, with no motivation for a season, but I actually am in a pretty good spot with my arm. I’ll be fine. If they need me, I’ll be ready.”
Kershaw said he has kept in touch with his old Dodgers teammates, with some connecting on video calls from the weight room or clubhouse at Camelback Ranch. He arrived in the Phoenix area two days before the workout, but he skipped a trip to Camelback Ranch.
“I’ve thought about it,” he said. “I miss the guys. I think it’s probably just better, at least for this first year, for me mentally to just stay away, just for spring training.”
Kershaw said he would be at Dodger Stadium for the championship ring ceremony March 27.
He is content with what he calls “Dad life.” He and his wife, Ellen, just welcomed their fifth child, and Dad life includes lots of shuttles to baseball and basketball practice.
“I run an Uber service,” Kershaw said.
This wouldn’t be a Dodgers story these days without some reference to the team’s big spending so, for what it’s worth, Kershaw spent some time Tuesday chatting with Skubal, who will be the grand prize on the free-agent market next winter, or whenever the likely lockout might end.
That’s a rational explanation, Kershaw says, for Skubal pitching just once in the WBC.
“Everybody knows the situation he is in, contract-wise,” Kershaw said. “Any innings we can get out of him is a huge bonus to this team. He’s great. Super competitive. We’re honored to have him.”
Should we assume Skubal will be pitching for the Dodgers next season? Kershaw laughed.
“No comment,” he said, then walked away to get ready for the first game of his post-retirement life.

Charles Barkley scolds sports fans for getting wrapped up in Olympic hockey frenzy
NEWYou can now listen to Fox News articles!
Basketball Hall of Famer Charles Barkley sounded off on the frenzied reactions to the U.S. men’s hockey team getting invited to the White House by President Donald Trump.
Trump talked to the Olympic gold medal-winning team immediately after they defeated Canada in overtime last weekend. He said they would be invited to his State of the Union address and added that he needed to invite the women’s team as well or he would be “impeached.”

Trump critics took the joke as a shot at the women’s team, which sparked questions from NHL and Professional Women’s Hockey League reporters as the players returned to their respective club teams.
“I’m proud of the United States men. I’m proud of the United States women. You should have invited both of them to the White House, but it shouldn’t have been disrespect, misogyny,” Barkley said on the “Steam Room” podcast. “Like, yo, man, why do y’all have to mess everything up? Everything isn’t Democrat, Republican, conservative, liberal. That’s why we got this divided, screwed up country. Stop it man. Because, you know, the public, they’re idiots. They’re fools. They can’t think for themselves. I know y’all say stuff to trigger them. Y’all say stuff and y’all know they’re going to be fools.”
Barkley lamented that the average person would get riled up over the supposed controversy.

“We don’t have to fall for stupidity. But we do – that’s my point. These people out here are stupid. They need something to trigger them. Just because they want us to be stupid. We don’t have to be stupid. He should have invited both teams to the White House. Simple as that. Guys who didn’t want to go shouldn’t have to explain why they didn’t go.”
The former Philadelphia 76ers, Houston Rockets and Phoenix Suns star made clear he would go to the White House regardless of whether Trump was in office.
“I’ve said this before, I’m not a Trump guy. But if I got invited to the White House, I would go. I’m not a Trump guy – I want to make that clear. But I respect the office,” Barkley said. “He’s the president of the United States. But if guys don’t want to go, I understand that too. It doesn’t have to be a talking point. It doesn’t have to be un-American.
