Beaty didn't do him any favors either with the QB rotation.
I don't buy this one bit. The old saying is "If you have two Quarterbacks, you really have none" and it fit here perfectly.
Cozart nor Willis could separate themselves from each other. They both made incredibly dumb decisions and were not progressing enough to justify giving either the job. There is a reason that we never won a game with Willis starting, and while yeah, the team was terrible, every team SHOULD win a game or two now and then (see UT 2016).
I hope Willis the best, but this reminds me exactly of when Jordan Webb left. Everyone wanted to blame Weis for not giving him a fair shot, but the truth was, as he showed at Colorado, he just wasn't that good.
