What's ironic is that just the other day I was having a conversation with someone about how little it really matters who the third-string quarterback is.

Unless, of course, your backup gets hurt.

That's what happened to BYU this week with backup quarterback Brenden Gaskins breaking his finger. He may yet be the backup against Arizona (provided he can throw with a splint on his finger) but suddenly it DOES matter who's No. 3.

We got a quick look at the four quarterbacks competing for the spot on Tuesday. I thought James Lark and Jason Munns looked the best, with Kurt McEuen and Sam Doman not really getting enough work to form a real opinion.

Munns had an interesting high school career. His sophomore and junior years were brilliant but he had a very young team around him as a senior and his stats fell off. But he sure passes the eyeball test: He's tall, fluid and just looks like a quarterback. His throws today were on the money and had some velocity on them. I saw some of his high school highlights and he looks pretty mobile.

It's worth watching this next week who impresses the coaches during team and skeleton.

I was also impressed by freshmen defensive linemen Eathyn Malulameuna and David Angulia. Depth is an issue at defensive tackle and these guys might be forced into action.

Funny moment: Freshman cornerback Brannon Brooks made a play on a deep ball but instead of picking it off he knocked it down with both hands. His teammates teased him, saying "This ain't volleyball!"
