Washington vs. UCLA College Football Week 5

Friday at 7:30 p.m., UCLA football (4-0) will kick off its Week 5 contest against No. 15 Washington (4-0).

Here are the most questions that we'd like to have answered by the end of the Week 5 game.

Can the Bruins' long DBs step up? -The Bruins' coaching staff and social media accounts hyped up their length in the cornerback room before the season began. - So far this season, Washington has won a lot of jump balls and made a lot of deep passes. If UCLA is going to win, they must limit those, and the length of their cornerbacks will play a significant role in this.

Who will win the battle of star QBs? -Dorian Thompson-Robinson and Michael Penix Jr. will never be on the field at the same time, as is customary in head-to-head quarterback battles. -That may be an excuse for players to avoid media questions, but it is still a major talking point heading into Friday night. -This will be their first and only meeting, barring a rematch in the Pac-12 championship game, and it should be an entertaining, high-scoring affair.

Will UCLA rise to its first real challenge? -The Bruins' first four weeks of the season were merely a warm-up for the real competition, despite how often it has been mentioned over the past few months.

Washington enters the game on Friday with a 4-0 record that was boosted by victories over then-No. 11 Michigan State and Stanford, a team that is ranked right next to South Alabama at No. 63 in the FPI. Beating the Huskies would be a serious, legitimate win for the Bruins, and it would likely vault them into the top 25 next week.

If the Bruins don't prove themselves to be true contenders sooner rather than later, a 4-0 season could turn into a 4-3 season, and it all starts Friday night at the Rose Bowl.
