Roman Tillmon arrives in Boise with a clear job and an even clearer mindset.
The senior transfer from South Dakota is expected to start at nickel for Boise State, giving the Broncos a hard-hitting presence in the defensive backfield. At 5-foot-11 and 195 pounds, Tillmon brings production, too. In his final season with the Coyotes, he finished second on the team with 94 total tackles and led South Dakota with 45 solo tackles.
Boise State will also see him line up against his old team when South Dakota visits on Sept. 19.
Tillmon’s path to this point wasn’t built on early hype. He said Thursday that he felt he was “under-recruited” coming out of high school and went most of the process without a Division I offer until South Dakota came through late.
He took the chance, became one of only eight true freshmen to play for the Coyotes in 2023, then appeared in all 14 games as a sophomore. Last season, he started all 15 games at safety as South Dakota reached the FCS quarterfinals.
Now he’s making another transition, this time to nickel, a spot that should let Boise State use his tackling ability in more ways. The role can send him on blitzes or pull him into the run fit as an extra defender.
“Roman, man, he’s done a good job. He’s a guy that’s played safety and corner in his career, so he’s a versatile DB,” defensive backs coach Terrence Brown said in April during spring camp. “And that’s what the nucleus of the position is: a guy that has a lot of versatility.”
Tillmon said Thursday that the move has come with a strong focus on the details, and he’s leaned into the coaching since arriving in Boise.
“I want to be great, so I’ve got to do things that will allow me to be great,” Tillmon told reporters Thursday. “Our coaches talk about that a lot, so anything that they’re teaching or coaching, I’m applying it to my game and being coachable.”
He also laid out a few of the areas he wants to sharpen before Boise State opens at Oregon on Sept. 5. One is forcing more turnovers in 2026, which has meant working on stripping the ball and punching it free.
That includes the Peanut Punch, named for former Chicago Bears defensive back Charles “Peanut” Tillman, and Roman Tillmon has been drilling the technique with edge coach Jabril Frazier, who has been reading and conducting studies on how to generate the most power for it.
“Whenever I’m at practice, just really making sure I’m having my elbow over my wrist, punching the ball out, trying to see if I can create more physicality toward the ball,” Tillmon said.
He’s also spending time with the JUGS football passing machine to sharpen his hand-eye coordination and improve his ability to track and catch the ball.
“A lot of things can just be like your feet positioning or getting your eyes to the quarterback,” Tillmon said. “Just stuff that will put you in position to make the play first, because you’ve got to be in position to make that play.”

Boise State Legend DeMarcus Lawrence Nears The End Of A Dream NFL Run
DeMarcus Lawrences long NFL journey is heading toward its final chapter, with the former Boise State standout saying he plans to retire after the 2026 season. For Broncos fans, it is the kind of announcement that makes the pull of the past feel close again, because Lawrence turned his Boise State success into an 11-year run with the Dallas Cowboys before moving on to the Seattle Seahawks last offseason.
Lawrence has stayed productive deep into his career, earning Pro Bowl recognition and stacking up the kind of defensive numbers that helped make him one of the more accomplished linemen to come through Boise State. His move to Seattle also brought a championship payoff, as he helped lead the Seahawks to a Super Bowl victory, and now the only question left is how he wants the final stretch of that dream run to end.

Boise State Faces 3 Early Pac-12 Threats To Its New-Look Dominance
Boise States move into the Pac-12 changes the conversation around the Broncos almost immediately, especially after the run Spencer Danielson has built in Mountain West play. The league they are entering will look a lot like familiar ground, too, with several former Mountain West programs now in the mix and a few early matchups already shaping up as the kind that could test Boise States new-look dominance in 2026.
Fresno State and San Diego State have long been familiar hurdles, but Texas State adds a different kind of problem because of the offensive talent it brings into the conference picture. Boise State will have to navigate a group of teams that already understand its style, know its standard and, in some cases, are arriving with enough recent momentum to make the Broncos prove they still sit alone at the top.
