BYU’s defensive tackle room finally looks built like a real Power 4 group, and that alone is a shift worth noticing. The Cougars have spent years trying to patch together the position, and the results have usually been more theory than production. This time, the depth chart actually carries some weight.
The headliners are impossible to miss. Keanu Tanuvasa, Justin Kirkland and Anisi Purcell are all fifth-year seniors, and the top three tackles in the room have combined for 4,000 career snaps.
At just over 6-foot-3 and 305 pounds on average, they bring the kind of size that forces offenses to deal with them snap after snap. There’s experience here, but there’s also real skill.
For once, BYU is not leaning on a converted defensive end group trying to survive against a Power 4 schedule.
Tanuvasa arrived as one of the summer’s bigger wins and earned preseason first team all-conference honors. He finished third among Big 12 defensive tackles in total pressures.
Kirkland missed most of 2025 with an injury, but before that he was the eighth-best run defender at his position in the Big 12 per PFF, and he has said he wants to break the NFL combine record of 49 reps of 225 pounds on the bench press. Purcell added his own impact last season, finishing fourth on the team in sacks even though he played the 10th most snaps as a pass rusher.
The next wave gives this group some real shape. Junior Viliami Pouha posted the highest pressure rate among BYU defensive tackles last season, and redshirt freshman Uluvai Feituli came in as the most highly regarded recruit in the bunch by a wide margin. If the top end develops the way BYU believes it can, this room has the ceiling to change the profile of the entire defense.
That said, the production still has to show up in the places that matter most. BYU was solid against the run last season, but not dominant, finishing 31st in EPA per rush, 34th in success rate against the run and 46th in yards per carry allowed. The defensive tackles were not the whole issue, but they were not the answer either.
Tanuvasa became the face of that frustration for a lot of people. The former Utah transfer was one of the most celebrated additions BYU has made in recent memory because he was supposed to be more than a space-eater.
Instead, his stop rate fell from 7.7% at Utah to 2.9% at BYU. The source of that drop may have had more to do with the situation around him than his own ability.
Justin Kirkland’s injury forced BYU into more three-man fronts than expected, and Tanuvasa ended up playing more than twice as many snaps at nose tackle as he had in his previous three seasons combined. That meant more double teams, and more double teams meant fewer chances to create disruption.
With BYU now able to go five deep at defensive tackle, Tanuvasa should have more room to do what he does best. He had 2 sacks and 2 QB hits last season, and the comparison point in the Big 12 is AJ Holmes, who led conference defensive tackles with 5 sacks for Texas Tech.
That’s why this group lands at No. 9, just ahead of the wide receivers. The floor looks strong, and Tanuvasa and Kirkland may be the most complete pair of defensive tackles BYU has had in the Kalani Sitake era.
Both have spent their careers at the position and both have shown they can handle Power 4 football for more than one season. That matters.
But until the tackles are producing more than just tough snaps and heavy contact, there are still other spots on the roster with more proven upside and better history behind them.

Preston Rex Is Giving BYU A New Option Behind LJ Martin
Preston Rex arrived at BYU as a defensive back, but his path took a notable turn before the 2025 fall camp when Kalani Sitake asked him to move to running back. Rex accepted the switch and has already shown he can help in a different role, giving the Cougars another piece behind LJ Martin with the ability to contribute both on the ground and as a receiver.
Now fully healthy and looking ahead to the 2026 season, Rexs emergence matters because it adds flexibility to BYUs backfield. The Cougars have reason to like a player who embraced a position change, learned quickly and found a way onto the field, especially with more opportunity potentially ahead as he settles deeper into the offense.

BYU Faces A Special Teams Problem That Could Shape Its Season
BYU enters the season with a lot of familiar pieces back in place, but special teams has become one of the few real questions hanging over the roster. The Cougars have to remake key spots all at once, with a new special teams coordinator in Justin Ena overseeing a group that will need to find answers at kicker, punter and return specialist before the games start to matter.
The early evaluation has given BYU a small cluster of names to watch, including Matthias Dunn and Brody Laga in the kicking mix, Fuller Shurtz and Cole Shulman at punter, and Ty Smith handling long snapping. It is the kind of depth-chart churn that can fly under the radar in August, yet it can swing field position and close games once the season settles in. For a team with bigger ambitions, getting this part right could end up mattering more than it first appears. [Read more 🡒]
