OKLAHOMA CITY (AP) — Vanderbilt coach Mark Byington expects a hostile environment when the Commodores play Nebraska on Saturday in the second round of the NCAA Tournament.

Byington is well aware of how Nebraska’s fans flooded Oklahoma City’s Paycom Center for a first-round game. A sea of red witnessed history on Thursday as Pryce Sandfort led the fourth-seeded Cornhuskers (27-6) to a 76-47 victory over Troy for their first-ever tournament win.

Byington said his fifth-seeded Commodores (27-8) will need to stay connected and lean on their experience to deal with the atmosphere. The arena is just a six-hour drive from Nebraska’s campus in Lincoln, and Cornhusker fans took advantage by creating a caravan down Interstate 35.

“I think it’s neutral by name only,” Byington said. “This is going to be a road game. I heard reports. They said it was even better than the home games in Nebraska — the noise, the environment.”

Nebraska entered March Madness as the only team from a power conference without an NCAA Tournament win. Now, the loyal fanbase wants more. Nebraska guard Sam Hoiberg believes the crowd could be more intense on Saturday.

“I think it’s going to be maybe even louder, because people are going to be off work and come down for the weekend,” he said. “Yeah, we fully expect to have another amazing crowd, but you can’t rely on that to win a game. You have to still execute and focus on the game plan.”

Vanderbilt, which rallied to defeat McNeese in the first round on Thursday, has faced tough environments this season, and things have not gone well. The Commodores played Southeastern Conference road games against NCAA Tournament teams Texas, Arkansas, Missouri, Kentucky and Tennessee and came out of those contests with a 1-4 record.

Big Red shenanigans

Hoiberg addressed a Nebraska fan jumping into the Bricktown Canal in downtown Oklahoma City on Thursday night.

“I saw one guy jumped in the canal last night,” he said. “Yeah, they (Nebraska fans) took over. It’s almost like they didn’t want the day to end, you know? That was fun to see all that stuff, although I’m guessing he got in a little bit of trouble for doing that.”

‘Better and better’

VCU has kept winning since mid-February, including a run through the Atlantic 10 Tournament to get a bid to March Madness and set up its massive comeback from 19 down to beat sixth-seeded North Carolina in overtime. And coach Phil Martelli Jr. had a clear message about what could be ahead for his 11th-seeded Rams (28-7) entering Saturday’s second-round game against Illinois.

“What I told those guys is every time you win in March, the wins feel better and better and better as you go along,” Martelli said. “Last night felt pretty good. Winning the championship felt good. Last night felt a little bit better.

“I told them, if you want to feel a pretty sweet feeling, you go get No. 2 tomorrow.”

That said, the pressing challenge is stopping an offense ranked No. 1 in KenPom’s adjusted offensive efficiency by averaging 131.7 points per 100 possessions.

“One thing I know about these guys is they’ve responded to every challenge and they’ll be ready to go,” Martelli said.

The third-seeded Fighting Illini (25-8) faced the least drama of any winner in Thursday’s four first-round games in Greenville, South Carolina. Illinois advanced with a 105-70 win against Penn after shooting 50% and making 15 of 36 3s (.417), while the Illini dominated the glass (48-25) with their size.

“We have so many versatile players on the team that we kind of spaced the floor, and we were able to pick the defense apart with our skill,” guard Andrej Stojakovic said.

This is Illinois’ sixth consecutive NCAA bid. The Illini have failed to reach the second weekend in four of the previous five years, the outlier being a run to the Elite Eight two years ago before falling to UConn on the Huskies’ romp to a second straight national title.

Another Cinderella run?

VCU looks to add to its long history of tournament upsets.

Illinois is a 10 1/2-point against VCU, favorite according to BetMGM. But VCU has a long history of pulling shockers during March Madness.

In 2011, the 11th-seeded Rams got all the way to the Final Four, defeating No. 3 seed Purdue and No. 1 seed Kansas along the way. In 2007, No. 11 seed VCU knocked off No. 6 Duke in the first round. In 2012, No. 12 VCU defeated No. 5 Wichita State in the first round.

Almost home

Houston is one win from going back home for the Sweet 16.

The Cougars (29-6) will face Texas A&M (22-11) in the second round Saturday in Oklahoma City. If they win, they would then need two wins at the Toyota Center in Houston — just a few miles from campus — to return to the Final Four.

The Cougars have fought the urge to look ahead from the moment the brackets were announced. They looked focused when they rolled past Idaho 78-47 in the first round on Thursday.

They’ll face a tough Aggies team that defeated Saint Mary’s 63-50 on Thursday.
