Attitude and talent-wise, Wilson did real good things for IU. And The offenses of '12, '13 and '15 were fun to watch and difficult for opponents to play. Too bad he couldn't bring in a BT level qb in those years while losing Trey to transfer and Sudfeld to gradation. Just Average defenses would have produced a couple more wins in each of those years.
The biggest reason IU made it back to a bowl game in '16 was the defense that TA worked miracles with in his first year. The O had a few decent games, but overall the D won the MSU, PU and Rutgers games. The O ranked near the bottom nationally in '16 in Red Zone efficiency due to frequent RL picks, Oakes having a bad year, injuries to the OL resulting in a poor run game. By mid-season, due to these struggles, Wilson had to turn to the Big Bacon/Diamont package to not only score, but hold onto the ball in red zone.
I thank Wilson for his time and effort in turning around the attitude. A shame he couldn't over come his off field issues and injured players stance. Has worked out well for him at OSU and for TA at IU.
Oh, and I have liked the fact that upon all his ex-IU players' graduations, he has mentioned how proud he is of them on Twitter.
