Run game: B+. He's been effective in the run game when he decides to keep the ball, and has made pretty solid reads for most of the year. There are bad reads here and there, but his running game has improved significantly from last season. He's lost one fumble this year by my count, which isn't terrible, considering how often we've fumbled the ball in the past.
Passing game: C-. His deep ball has been pretty good for the most part, sadly, the deep ball by design is a low percentage play to begin with. It's a good weapon to have, but chucking the ball 35 yards down field isn't a passing offense you want to make a living on. His short routes are inconsistent, and his swing passes are very poor. He also doesn't read defenses well and tends to lock into a guy without surveying the whole field. His mechanics are inconsistent, but fixable. His INTs are down this season, but he's been on the good side of some drops by DBs and LBs.
Overall, I'd give TA a B- on the year so far. He's got to get better at throwing the ball for Nebraska to truly compete with Michigan State or Ohio State in Indy though, otherwise I don't know if you can win the conference with our passing attack at this point.
