No. 8 UCLA football needs QB Ty Dieffenbach to be the difference

21 minutes ago 2

LOS ANGELES — As the football season progresses – as quarterback Nico Iamaleava’s knee injury moves further in the distance – and as more film comes out, the element of surprise is gone for UCLA’s Ty Dieffenbach.

Everyone knows who he is.

The unflappable backup who helped UCLA upset Oregon. The hometown hero who’s leading his dream school to the College Football Playoff. The dynamic quarterback who relies on his athleticism – a little too much at times. The gunslinger who identifies the pre-snap coverage, but gets jumpy when forced to progress through his reads. The often slow starter who’s emerged in the clutch.

After three starts for the 6-foot-6 senior, defenses understand Dieffenbach’s tendencies and have found ways to confound him. It didn’t matter against Michigan State or Nevada, but when No. 8 UCLA faces Minnesota on Saturday in Minneapolis, a struggling passing attack could be a greater crux.

The Golden Gophers (5-3, 3-2 Big Ten) have the pieces to stymie Dieffenbach and the offense and the talent to capitalize if the Bruins (8-0, 5-0 Big Ten) can’t move the ball through the air.

“This is a giant week for him and the receivers to get on the same page, and start clicking on all cylinders,” UCLA head coach Bob Chesney said. “It’s time.”

Dieffenbach’s confidence carried him in relief of Iamaleava against Oregon. After defeating Wisconsin, the former Agoura High star emphasized he was ready for this opportunity, one he’s been waiting for it since he was the kid in the Rose Bowl watching the Bruins dance to “California Love.”

Over the past two weeks, he seems to be thinking more.

“Had some opportunities in the pass game where you just got to pull the trigger and trust,” Chesney said. “We’re a little off.”

Dieffenbach was held to less than 200 passing yards and a 60% completion-percentage in each of the last two games. He’s showcased elusiveness in the pocket to keep plays alive, but hasn’t turned that into downfield runs to gain yards or first downs. UCLA converted only 11 of 29 third-down opportunities. But with the defense forcing seven turnovers, it’s masked the passing game’s woes.

“Now there’s a lot of tape on film,” Bruins offensive coordinator Dean Kennedy said. “There’s going to be a lot of different defenses. That’s probably the biggest piece, is trying to identify the multitude of coverages that you can see at this point in the game. We do have to take it to the next level of, how do you attack each shell.”

Kennedy explained the next steps for Dieffenbach are to shuffle through his reads and trust the pocket.

The Bruins’ inability to move the ball has resulted in slow starts. The defense flipped the field – and even scored a touchdown of its own with Derrick Barksdale’s pick-6 against Nevada – helping to build leads. Then UCLA closed out games with its rushing attack.

Dieffenbach has hit big plays in the second half. He found Brian Rowe Jr. for a 63-yard touchdown against Michigan State. He led a 97-yard game-sealing drive against Wisconsin with downfield completions to wide receivers Landon Ellis and Semaj Morgan.

But if the offense can’t get it going early against the Golden Gophers, it could put them in a place of desperation.

“We’ve just got to come out with a different mindset,” Kennedy said.

At this point of the season, margins are thinner. In Tuesday’s first reveal of the 2026 College Football Playoff rankings, UCLA was slotted No. 8. It’s an impressive place for a program that stumbled to a combined 8-16 over the past two seasons, but leaves the Bruins vulnerable to falling out of the CFP’s coveted top 12 with any loss.

Now that it’s officially crunch time, UCLA isn’t resting on that achievement, understanding any blip can take it away.

“When you’re 8-0, that doesn’t mean that you relax,” Chesney said. “At 8-0, it means the standard’s got to raise.
