PROVO — A lot of the talk around BYU has been the offense's inability to advance past midfield in the Cougars' 27-0 loss to LSU.

Offensive coordinator Ty Detmer knows much of the criticism has been put on him and quarterback Tanner Mangum as faces and leaders of the offense — and he's willing to accept it, evaluate it and make changes as needed.

“There’s part of you that just wants to put it away and forget it. The other part says we need to learn it, fix it and figure out what we need to do differently," Detmer said.

“You don’t put too much stock into it; I feel like we are a better team than what we showed. But you want to learn from it, show the players their mistakes and clean it up.”

And even though the defense fared a little bit, BYU defensive coordinator Ilaisa Tuiaki is taking blame on himself, too, after allowing the Tigers to pile up 479 yards of offense. LSU was just 3-of-7 in the red zone against BYU — but Tuiaki isn't counting it as a win and vows to do better.

“Overall, it wasn’t as bad as I think the score showed," he said. "I thought the kids battled until the end, and I was really happy with that.”

It's been a solemn three days of post-LSU hangover in Provo, at least among the fanbase and outside the walls of the student-athlete building. Coaches and players have even admitted they took the worst loss since 1974 harder than some others — who wouldn't?

But it's time to get back to work, Mangum said.

"We weren’t happy at all with how we played. But we’ve got to use that as extra fuel to come back and get back to work," he said.

“I think guys are excited for another opportunity to come back and try to play our game.”

Burt makes a move

Riley Burt won't be coming out of the offensive backfield at BYU anymore.

The redshirt sophomore from Mantua has moved to the defensive backfield, Tuiaki confirmed Tuesday after he was seen warming up with the cornerbacks prior to last week's game in New Orleans.

It might not be his last move, either.

"We felt like it was a better fit for him," Tuiaki said. "We moved him to corner, going to try him there first, and then the natural progression is to safety or linebacker or defensive end. Just test his hips and see where he is.”

Burt showed flashes of strong play at running back, but in two seasons (with a redshirt), he ran for just 86 yards on 14 rushes.

Burt's first full-time game in the defensive backfield could come as the Cougars are reeling from the loss of safety Micah Hannemann for the first half against Utah. Don't expect Burt to line up at safety for that half — but a familiar face to the Utes might.

Austin Lee has been cleared to go full-bore for the Cougars this weekend, and he'll line up in Hannemann's spot. The 6-foot sophomore played his freshman year at Utah, collecting four tackles on special teams in seven games, before transferring to Salt Lake Community College and then to BYU this spring.

Marvin Hifo, who had a team-high 10 tackles against the Tigers, is also an option, as is defensive back Tanner Jacobson. The older brother of BYU receiver Aleva Hifo played two years at Mt. San Jacinto College in California, finished his associate's degree for a year, and joined his sibling at BYU for one final season of eligibility.

"He has one year to play, and he was just jacked up to be on the team and play special teams,” Tuiaki said of Marvin Hifo. “We thought that he’d be a special teams guy, but he’s a great tackler and a great energy guy. He’s really, really good in the locker room.”

Detmer knows how to handle loss

Wide receiver Jonah Trinnaman told the media Monday that Detmer isn't the kind of coach who throws chairs or gets in his players' faces after a disappointing loss like last weekend.

But don't think he doesn't know how to handle disappointment.

Detmer's first start for the Detroit Lions in 2001 may be one of the worst in NFL history. He threw seven interceptions that game, which still ties for the second-most picks in single-game history.

But Detmer also knows the value of dwelling too long on mistakes.

“We don’t have much time to dwell on the past," he said. "We’re on to Utah now.”
