Ty Dieffenbach fought through the pain to lead No. 4 UCLA to victory over Illinois

PASADENA, Calif.  – Senior quarterback Ty Dieffenbach has been the rock in the storm for No. 4 UCLA (10, 7-0), a local kid who's become one of the best stories on a team that itself is the best story in college football. 

But when he and the Bruins suited up against Illinois (6-4, 4-3), he gave the now-packed Rose Bowl a scare just before halftime when he went down with a wrist injury that kept him off the field while sophomore Madden Iamaleava took the reins.

 How Dieffenbach came back to the game, though, says everything about the leader he's grown into and about the toughness Bob Chesney's Bruins. 

As the third quarter came to a close, the Rose Bowl, soaked in rain yet filled with fans, suddenly erupted into cheers that didn't reflect the attitude of a team holding on to a tight 12-7 lead. But when Chesney saw Dieffenbach on the big screen, he understood the noise.

The hero returns

"When Ty walked in, I didn't know what it was. Then I saw up on the screen him coming down the sideline. That was pretty impressive," Chesney said. 

That reception was a surreal moment for Dieffenbach, one that says everything about the circumstances that have led him to this moment. A native of Agoura Hills, CA, he'd grown up dreaming of playing in the Rose Bowl one day. 

He began this season as a third-string quarterback and transfer from Cal Poly. Suddenly, he was thrust into the spotlight when senior quarterback Nico Iamaleava went down for the season with a torn ACL. Starting from the second half of UCLA's win over Oregon onward, the Bruins' still-perfect season was in his hands. 

Now, he's a bonafide celebrity and America's Stadium treated him to a hero's welcome when they knew he was going to be okay. 

"That crowd reaction was unbelievable. That was one of the best moments of my life," Dieffenach said.

Getting back at it

He didn't waste any time once he was back, either. 

While Dieffenbach's first half was a mixed bag that featured both the high of a 54-yard touchdown pass to senior wide receiver Aidan Mizell on the fifth play of the game to the low of an interception in the end zone that spoiled a golden opportunity for another UCLA touchdown in the second quarter, his return was one marked by an eagerness to get things going again.

He came back on the field officially right at the end of the third quarter and eight plays later in the fourth he threw a 26-yard dime to senior receiver Semaj Morgan for UCLA's second touchdown of the night, some much-needed insurance to keep the Fighting Illini at bay. 

"Once I got on the field, all of that pain went away with that adrenaline. That's just how it is," Dieffenbach said. "Just to see them on that third down, find one for that touchdown was a big deal."

A leader of men

Dieffenbach took the field for every UCLA drive after that, all the way to end of the 22-14 Bruin victory, but it was what he did before he had the ball back in his hands that made the most impact on UCLA, who for the first time seemingly all season seemed the slightest bit shaken. 

He raced down the field, high-fiving every teammate he could while the crowd cheered for him. For so many teams, the quarterback is the heartbeat of the squad and seeing your heart go down can crush the morale of everyone else. 

Dieffenbach lifted the morale back up and his team responded. He's come a long way from rising to the occasion against the Ducks. He's UCLA's leader now and he wasn't going to let his team go without him.

"That's leadership. That stands out," Chesney said. "The confidence that I think everybody gained from that… I think that's where he's grown the most: he went from going into that Oregon game and having a lot of confidence in himself, but now I think others have confidence in him."
