Matt Cassel's stats without an offensive line full of Pro Bowlers and Dwayne Bowe and Moeaki (rookie TE) as his only real receiving threats.

Just throwing that out there.. Say what you will about the skill players around Brady, but the Patriots know how to get guys that fit their system. Whatever system they decide to run from year to year. The offensive line gives Brady like 6 seconds to throw the ball almost all the time. It doesn't matter who you have out there, they will get open eventually. These guys just happen to be small and quick and get open fairly easily.
I'm no lover of Matt Cassel, but with how he has played in the past 10 games or so, I'm starting to drink the Kool-Aid. This guy has fire and goes out there and plays his ass off. He reminds me a lot of Brady in that way. They play like every game might be the last one. That's what wins MVPs. Brady will get it this year but watch out for Cassel. If the Chiefs get him a legit WR threat to go with Bowe and another good lineman, he may be the best QB to come out of the entire Pete Carroll USC years.
