Ever since Brady went down, I have been interested to see when this debate would begin.  Obviously, if the Pats do well without him, he's probably not as good as we all thought and if the Pats do horribly, than Belichick isn't the great coach everyone made him out to be. 

Personally, I expected the Pats to do worse because I thought their success had more to do with Brady than the system.  Now that Cassell is throwing for 400+ yards against good defenses, you have to start wondering about Brady.  Of course, if Cassell goes on to become an all-pro QB, than it's both a good system with good QB's (think Montana giving way to Steve Young).  But if this proves to be the best Cassell ever plays, you have to think that Brady just isn't as good as everyone had been saying for the last few years.

Okay to be honest, I just wanted this argument to come up so that we can continue to proclaim Peyton as the number one QB of the generation.
