GLENDALE, Calif. >> In the Los Angeles haze, the Hawaii football team has a clear purpose for today’s game against UCLA in the famed Rose Bowl.

“It doesn’t matter if we’re playing at (UH’s) Cooke Field or the Rose Bowl,” coach Nick Rolovich said. “It’s the same 100-yard field. And I think the team has the maturity to realize that. I hope they’re not in awe because it’s a pretty cool place to play in.”

Last year, Rolovich allowed Instagram opportunities when the Rainbow Warriors had a walk-through session in advance of the game against Michigan in the Big House. For this trip, the Warriors practiced on their campus through Thursday, arrived in Southern California that evening, and had a walk-through session Friday at Cathedral High near Dodger Stadium.

A few Warriors have experienced the aura of the Rose Bowl. Right tackle Fred Ulu-Perry played eight games as a freshman for the Bruins in 2015 before requesting — and receiving — a release from his scholarship to transfer to UH. Right wideout Ammon Barker took a recruiting trip and made a verbal commitment to sign with the Bruins in 2013. But that offer was rescinded when the point recruiter left UCLA to coach at Washington. Offensive lineman Matt Norman grew up 20 minutes from the Rose Bowl.

“I was a bit of a UCLA football fan before I got (to UH), but obviously not anymore,” Norman said.

Of the Rose Bowl, quarterback Dru Brown said, “There are a lot of good things that have happened there, a lot of tradition. It’ll be cool to play where a ton of great players have played. It’ll be a fun experience.”

The Warriors enter with several concerns. In the first two games, they have been penalized 20 times, with two infractions negating touchdowns. Rolovich said the self-discipline has been repeatedly addressed in practices and meetings.

“We’ll see what happens when it comes to game time,” said Rolovich, acknowledging, “I’m disappointed. I don’t like wasting my breath. I think they realize if we do that again, we’ll definitely lose this game. (UCLA is) not a team where we can give things away and expect to win. This team is good.”

Rolovich marveled at the Bruins’ defense, particularly the interior linemen, and tight end Caleb Wilson, who had 15 catches for 208 yards in last week’s 45-44 comeback victory over Texas A&M. Then there is Josh Rosen, considered one of the top quarterbacks in the country. Rosen missed the final six games of the 2016 season because of an injury, but was at his best in the fourth quarter last week.

“Originally, I hadn’t watched him too much,” Rolovich said. “Sometimes I get under the impression that guys who are hyped early are kind of carnival quarterbacks, where they can throw the ball pretty. But what I saw in the second half of that game was toughness, the perseverance. I think he has all the qualities to be a great quarterback.”

Rosen told reporters that following the self-imposed 24-hour rule — win or lose, the Bruins move forward a day later — he critiqued his performance and began focusing on Hawaii.

“I just turned off my phone, went through all the text messages, and said thank you, and called my parents, and talked about it,” Rosen said of the attention following last week’s victory. “And (offensive coordinator Jedd) Fisch has a very unique way of humbling you. So I got in the film room, addressed what needed to be addressed.”
