4 things that pop out by watching those vids:
1 - in the Utah game, he was blitzed like crazy and to be honest, he looks really bad against it. He needs to get better calling protections or else he will be eaten alive in the pros. Obviously, better talent around him and system will help this flaw of him, but he will need to get better.
2 - it's great that he can play from under center, but I don't see lot of success in deep balls after PA, his arm is fantastic, but it doesn't translate to long completions. It works better at intermediate throws. The rollouts (and Wyoming ran a lot of them with Allen) are a nice playcalling counter punch, but you can't base your base offense off of them.
3 - Against Texas State he played a lot of snaps from the shotgun and his overall accuracy got better. It seems that he probably sees the field better in this formation.
4 - There's a snow game (Colorado State) and he takes over with his physicality, very tough to bring down in that environment.
