If Vick misses maybe a couple games and leaves early a couple times, this is a good spot for Young.
He's nowhere near as electric as Vick, but he can run and improvise. I think he's got a far stronger arm than some give him credit for and...him doing a Mike Vick imitation (with it being understood that he's a backup) seems like an ideal spot for him. He also has always had some curious throws go in the dirt and maybe Vick will point out he's doing something dopey there. I don't find their games to be extremely similar, but there's enough to the running and improvisation that I imagine he's in a good spot to learn.
He listened to and adores Mack Brown.
He listened to Fish. He didn't listen to his OCs in TEN yet listened to McNair and KC.
Mack Brown spent a bunch of time with him this offseason. It's everything that Brown set him straight.
If he doesn't listen to his Eagles coaches he is done in the NFL. This is a major issue.
Eagles fans are an extremely passionate group. VY seems to listen to every fan and digest it all in a very unprofessional self-defeating manner. I don't think you can be an NFL QB and behave as such.
