brady will never be the GOAT in my opinion because of spygate, deflategate and all of the other instances that the patriots have been caught cheating. Brady is a great quarterback, and Belichick is a great coach, but they are both cheaters. Always have been, always will be.
One, the crime of the Pats in Spygate is not that they did what they did (by all accounts it was a common practice in the league), it's that they were targeted and they got caught. Not really an advantage when every one is doing it, is it?
Two, BRADY didn't deflate the balls. Whether he knew about it or not has never been proven. And you have to account for the fact that his numbers were okay in the first half - with the allegedly "deflated" balls - and were LIGHTS OUT in the second half after the balls were brought back into code. (And it was never conclusively proved that it wasn't the environmental conditions of the game that accounted for the pressure loss, by the way).
Three, can you enlighten us on "all of the other instances"? I don't recall hearing about "all of the other instances". Must've missed those.
Bottom line is this: EVERY TIME the Pats get caught "cheating", and the world is watching them, they take it to the next level and win games they have no business winning. You don't cheat your way to the type of Super Bowl win they just had over the Falcons, nor the type of Super Bowl win they had over the Seahawks.
I suppose you're going to claim that Pete Carroll was on the Pats' payroll or something? Or Belichick had pictures of Carroll with a pretty coed, the USC mascot, and a bucket of Crisco?
