Based on what I've read/heard, if JP does end up unable to stay in the pocket and let the play develop then it won't be because our coaching staff (specifically Wyche) didn't prepare him. The approach seems to be that if they make him comfortable with as many scenarios as possible then he won't take off and give up on the play prematurely. I doubt they are trying to force him into the mold of a pocket passer (which would be a mistake at this point in his career) but they want to make scrambling an option only in cases A, F, and J (if you get my drift).
Make him aware of his options and he will use them. Scrambling will be one of those options...it just won't be the immediate reaction.
That's my impression of the idea anyway. No telling until he experiences it for real.
No comment on Vick though...I can't tell if I love or hate the way the guy plays from game-to-game.
