My gut says Coach wants Vick here, but the front office has said no.
The problem with Vick had a lot to do with his attitude. He thought the ball was better off in his hands. Period. So if his first option wasn't open, he'd take off and run with it. He never learned progressions, or was really forced to work on his accuracy. It's why his TE's always got the most catches, and everyone thought the Falcons WR's sucked. But truth is he didn't have the patience to let plays develop so he could get the ball into the WR's hands.
In some ways I think Vick is what Steve Young "could have been", if he had not come here and had time to learn behind Montana. Young got by early on with his legs, although he was never a "bad" passer. But his time learning the system and developing his overall Quarterback skills is what made him a Hall Of Fame player.
