I'm a bit late to the party, but damn Russ, after contributing that much solid info I felt like I had to contribute.
I see you've been big on AZ. As others pointed out, they had a really tough time putting away opponents. Two games lost (OSU, Stan) on last minute drives were pretty demoralizing.
However, when they've played USC these last two years, they've been tough as nails. Not many people remember it was 13-10 going into the 4th quarter at USC two years ago. Very well played game by the Cats, but a Gronkowski fumble let that victory slip away. Holding USC to 17 was not a fluke either this year. They do have the ability to step up when necessary, and I think getting to and winning that bowl game will give them a bit more heart when it comes to closing this year.
That said, Tuitama was the best QB they've had in forever and his numbers will be missed. But not many people realize that AZ had two plays: Gronkowski slant, or the short dump pass to the WRs. If you saw the BYU bowl game you saw Tui throw down field with great success. After watching him play all season, I was shocked to see him do that. Surprised the hell out of me. Matt Scott (I bet he gets the start) does not need to be outstanding in this system to win. The receivers do the majority of the work and the throws he will need to make won't be that difficult at all. Look for games to be won by methodically chewing up the clock and getting into a lot of third and short situations. Third and 10+ will be where AZ stuggles this year.
With two the RBs in Antolin and Grigsby, a mobile QB, promising WRs, and the #1 TE in the country, I don't think their offense will slip too much from last years production.
