I hate to think it and of course hope Vince comes back but... if I was the Houston Texans GM I'd hire Mack Brown as my head coach, trade David Carr for draft picks (to be used on offensive linemen) and draft Vince #1.
Vince returns to his hometown of Houston as the National Champion hero and #1 pick with his favorite coach.
As a diehard Orangeblood, I hope it does not happen.
