I might be an outsider but I've watched enough of your games to feel like I can comment.
Sherrifs is not the problem. He is a hard nosed kid who can make enough plays with both his arm and legs to win games in The AAC. He's never going to be confused for Tom Brady, but he doesn't have to be. The coaching staff needs to put him in a better position to be successful. They need to give him some easy completions early to get his confidence up. Bubble screens to Thomas or Mayala, screen pass to Newsome, quick slant to Thomas, A few short throws to the TE's. Get him going early in the game and he'll be more apt to survey the field a opposed to running when his first option is covered.
This board reads like every other college football board. Especially after a loss. All the coaches should be fired, and of course the back up QB is always the better option. Its a delusion that all football fan bases share. The thing is the starter is often the starter for more than what we see on Saturdays. He may have the best understanding of the offense, he may perform the best in practice, and may have the respect of his teammates. I suspect that is the case with Sherrifs. The fact that Andersen has played FB, Davis was moved to TE, and Williams' Shirt is a near lock to remain red tells me that Sherrifs is the guy.
