Brady is above average. He is far from the best QB the NFL has ever seen though. He's got probably the best offensive line the NFL has ever seen though. How many times has Brady been sacked this year? That's not a stat that goes to the QB, thats a stat that goes to the Offensive line
And look who he has to throw the ball to. And look at their running game. Don't get me wrong, I'm not saying the dude sucks, but put him on the Miami Dolphins and see if they have a winning season
