Oh and before the Pats fans try to defend their golden boy Brady, all I have to say is thank God for 2008. Compare Cassel that year to how Brady did his first year for the Pats...
Brady's first season: 264/413, 63.9%, 2843 YDS, 18 TD, 12 INT, 86.5 QB RAT
Cassel's first season: 327/516, 63.4%, 3693 YDS, 21 TD, 11 INT, 89.4 QB RAT
Keep in mind that Matt Cassel hadn't started a game since HIGH SCHOOL. Yes, he was a backup in college! Cassel's 2008 Pats team somehow missed the playoffs at 11-5, but I'm willing to bet had they made it, they could have won the Super Bowl with the help of some bullshit along the same lines as the "tuck rule."
In 2009, Cassel got traded to Kansas City. He had 16 TD, 16 INT, and a QB rating of 69.9, which was 20 points less than his rating with the Pats.
I'm not saying that Cassel is better than Brady, but 2008 was proof that any decent QB can be really good in the Patriots offense. Brady is obviously good, but the best ever? LOL. Only Pats fans, or homos like Colin Cowherd, will say shit like that.
