Indianapolis — One of the most common questions prospects face from media at the NFL Scouting Combine is which players they model their games after. It provides a simplified scope in which to view a player’s skill set and potential scheme fit.

When Deshea Townsend was entering the league as a defensive back 25 years ago, he wasn’t studying Deion Sanders. That’s not who Townsend saw when he looked in the mirror, and there was no use pretending that’s who he could become. He needed someone who looked like him and played like him to better sense how he could perform at the next level.

The man he kept turning to was Aaron Glenn.

Admiration was mostly from afar, but in one instance, it grew up-close and personal. In a game against the Houston Texans in 2002, Townsend’s Steelers limited the opposition to 47 yards of total offense. That would be good enough for an easy win 99% of the time, but the Texans won the game handily, thanks to a pair of interception returns for touchdowns by Glenn.

Townsend would go on to put together a meaningful career of his own, playing more than a decade with the Steelers, where he won a pair of Super Bowls. Today, his continued admiration for Glenn has led Townsend to Detroit, where he’ll serve on the coordinator’s defensive staff as the Detroit Lions’ secondary coach and pass-game coordinator.

“He’s gonna be able to deliver exactly what AG wants on the back end,” Lions head coach Dan Campbell said this week.

Finding the right secondary coach has proven problematic for Detroit. They thought they had their guy in Aubrey Pleasant, but the relationship didn’t last two seasons. And Dre Bly, brought on board last year, was let go earlier this offseason. Up next is Townsend, who has eight years of experience coaching defensive backs in the NFL, including the last two with the Jacksonville Jaguars.

He only joined the team last week, so he hasn’t fully processed the players he’s inheriting. But his room is due for something of an overhaul, particularly at cornerback. With that in mind, the Lions have wasted little time putting him to work evaluating prospects for the upcoming draft as well as soon-to-be free agents.

Townsend’s philosophies are simple. He’s quick to point out there are only five core coverages, and he only has one non-negotiable.

“If you won’t tackle, you won’t play,” Townsend said. “That’s it. If it’s on the tape you won’t tackle, you can’t play. Ultimately, I’m just looking for guys that don’t shy away from contact, that’s willing to throw it there.”

Of course, he’s also looking for guys who can be sticky in coverage and mentally tough, but it all starts with physicality. From there, he’ll seek to foster a culture of camaraderie in the back end of Detroit’s defense. He wants accomplishments and failures to be shared experiences.

“I’m a big believer in we’re all in this together,” Townsend said. “So if you get a pass caught on your (watch), it’s just like I got a pass caught on me. I’ve been saying it for years, when one player makes a play, we all make a play. I think that’s how we have to be. …I think that’s what our unit is going to be. We’re going to play together. We’re going to play for one another. That’s what it should be about.”

The approach certainly worked in Pittsburgh, which long has been viewed as the league’s gold standard for culture. Townsend will try to bring some of what he learned under the tutelage of coaches Bill Cowher, Mike Tomlin and Dick LeBeau to Detroit.

“It’s just the mindset of being a champion,” Townsend said. “Can you be consistent? That’s the one thing that always helps. If you going to be any organization that’s trying to win it’s going to be similar. It’s similar paths to being a champion and being the best and being consistent. I think we see a lot of things the same way (in Detroit).”
