First off, Bledsoe was never EVER EVER as good as Brady is, EVER. Second, Bledsoe was on the downward part of his career, Brady is still in his prime. Also, Matt Cassell freaking blows. He throws a couple nice passes here and there, but you can bet the pressure he is under to replace maybe the best QB ever will get to him. Just wait until a couple of losses cause the Randy of old to come out, a guy who takes off plays and acts like a snitch. This could get real ugly and I think that is more of a likely scenario, then lightening striking twice for the cheaters and them lucking out into another stud QB.
No chance. Moss will pout, Cassel will try to force feed him, and defenses will destroy the backup qb.
