Basically, I'm hoping POB comes in and lights things up from Day 1 at this point. Either way, that's a win-win for the team. Either he starts, or if he's amazing, TA knows he's probably got a short leash and will have to be on top of his game to maintain his starting spot. He really has been too turnover prone, in spite of coming up huge in other moments and winning certain games with the team on his back. The Iowa game perfectly encapsulates all that is wrong with TA as a QB.
If I had my druthers, and TA was our starter, I'd run an offense very similar to what Auburn did with Nick Marshall or Cam Newton years ago. Not pure pocket passers, Malzahn protect their weaknesses with LOT of QB run game-- QB power, QB lead, zone read, everything. Lots of designed stuff.. We saw some of that this year, just not enough to maximize TA the runner -AND- mitigate the risk of TA the passer, IMO. Neither of those Auburn guys were afraid to take off if things broke down during a pass play, either.
My one hesitation is that TA is not as big as those guys. I've long been wary that TA wouldn't hold up for a full season being used in this manner. But at this point, what do we have to lose?
