Yeah, and Joe Montana was nothing without Bill Walsh. Remind me, what was Belichick as a head coach prior to Brady? Don't get me wrong, I'd want him running the Bears out of any guy out there but you can have the best system in the world and you still need good players to execute it. Belichick would be the first to tell you that. And Cassel had a decent year in 2008--as in he was a borderline top 10 QB in the league. Brady had the greatest season of a QB in league history with largely the same personnel. Let's not pretend Cassel went in there and duplicated what Brady did just because he did a decent job.
