Vrabel was competitive with Marcus Mariotta. Now that he has a competent QB, look at what he can do. If we had fired McDermott last year and hired Vrabel we'd be 10-2. He is that much better of a coach.
The real, real question is, how much say does Beane have in the players he picks. Does Sean tell him who to take and he takes them or does he actually just tell Sean, this is who you are getting.
