Kelly Poppinga’s first BYU defense does not need an August makeover. It needs to survive a change at the top without losing the habits that made the last two seasons work.
That is the useful part of Poppinga’s new comments to The Salt Lake Tribune. He said the defense will keep much of its existing base, with a few different wrinkles. That matches what he told the Deseret News in March: expect recognizable fronts and coverages, not a scheme demolition.
Good. BYU hired a new coordinator, not a new identity.
The harder job is preserving the output after Jay Hill left for Michigan. BYU allowed fewer than 20 points per game in both 2024 and 2025. Poppinga inherits that standard, a veteran core, and enough returning production that “new coordinator” cannot become a blanket excuse for September confusion.
The standard is sitting in plain sight
BYU’s official staff announcement supplies the cleanest baseline. The 2025 defense finished among the national top 25 in eight listed categories.
| 2025 measure | BYU result | National rank | What has to carry over |
|---|---|---|---|
| Red-zone defense | 70.4% | 6th | Make long drives finish with field goals or nothing |
| Red-zone touchdown defense | 40.7% | 6th | Hold up when the field gets short |
| Interceptions | 17 | 7th | Turn disguise and leverage into possessions |
| Turnovers gained | 24 | 14th | Keep creating extra chances without chasing the ball recklessly |
| Scoring defense | 19.1 points per game | 19th | Do not let one bad drive become a bad quarter |
| Third-down defense | 33% | 19th | Get off the field after winning first and second down |
That table explains why continuity is sensible. It also shows why continuity alone will not be enough.
Turnovers can swing from season to season. An interception total depends on pressure, coverage, quarterback decisions, tipped balls and a little chaos. Poppinga cannot order 17 more from the equipment room. The sturdier receipts are red-zone and third-down defense, because both demand repeated execution after an offense has already moved the ball or reached a favorable down.
If those rates stay strong, the defense still has a floor when the takeaways cool. If they slip, repeating last year’s turnover count becomes a much heavier ask.
Poppinga’s changes should be judged by timing
The new coordinator has described a familiar menu: man-free coverage, Cover 3, some Cover 2, pressure and multiple fronts. Fans will be tempted to hunt for a brand-new formation in the first open practice clip. That is probably the least useful way to track this transition.
The difference should appear in when BYU calls things and how well the players hide them.
Poppinga told the Deseret News that Bear Bachmeier’s faster processing has forced the defense to disguise longer and stay disciplined. That is excellent camp work. A quarterback who punishes an early rotation makes safeties hold their intentions. A quarterback who gets the ball out quickly makes a pressure package prove it has an answer behind the rush.
BYU’s defense does not need to win every practice period against Bachmeier. It needs those periods to expose bad tells before Arizona, TCU or Notre Dame sees them on film.
Watch the safeties before the snap. Watch whether a linebacker can threaten pressure and still reach his coverage landmark. Watch whether the front can change the protection without leaving an easy answer in the flat. Those details will tell us more than a breathless report that the defense “won the day.”
The staff structure matters here
Poppinga is not calling this defense alone in a dark room.
Kalani Sitake promoted Sione Po’uha to associate head coach and hired Demario Warren as defensive pass game coordinator and cornerbacks coach. The official announcement credits Warren with 18 years of coaching experience, including six seasons as Southern Utah’s head coach. His 2025 Boise State secondary allowed 175.6 passing yards per game, and his cornerbacks produced 10 of the Broncos’ 14 interceptions.
That division of labor gives BYU a sensible transition plan. Poppinga can own the full call sheet while Po’uha keeps an experienced hand on the interior front and Warren handles the weekly details of matching Big 12 receivers. It also gives the defensive staff somewhere to challenge its own assumptions. Continuity gets stale when everyone agrees too quickly.
The personnel supports the plan. Poppinga named veterans such as Isaiah Glasker, Cade Uluave, Evan Johnson, Faletau Satuala and Keanu Tanuvasa when discussing the defense with the Tribune. That is experience at every level, not a room being rebuilt around one star.
It also raises the expectation. A veteran defense should be able to carry more disguise without turning every check into sideline charades.
Three camp checks that mean something
The first is explosive-play control. Aggression is only useful if the back end prevents a missed pressure from becoming six points. BYU can be attacking without turning every snap into a coin flip.
The second is clean third downs. The final result matters, but so does the operation. Are defenders aligned before the snap? Does the rush keep the quarterback contained? Does the coverage force a throw short of the sticks rather than surviving an open receiver and a bad pass?
The third is red-zone communication. Condensed space changes route combinations and removes some recovery room. One busted handoff in coverage can erase three good plays. BYU’s 40.7% red-zone touchdown rate was too useful to treat as last season’s souvenir.
These are better checks than sack totals from a protected practice format or anonymous depth-chart buzz. They also connect directly to what Poppinga inherited.
Keep the defense. Prove the standard belongs to the program.
Hill deserves credit for what BYU built. Poppinga does not need to pretend otherwise, and his public comments have not sounded like a man desperate to repaint every wall.
His chance is more interesting than that. If BYU stays hard to finish drives against, gets off the field on third down and creates pressure without exposing the secondary, then the defense was bigger than one coordinator. The system, assistants and veteran players carried the standard forward.
If the same names spend September pointing at each other after busted coverages, the continuity pitch will not mean much.
That is Poppinga’s first fall-camp test. The shape can look familiar. The results still have to be earned again.
