Ohhhhh, this discussion.
Coming from a Packers fan, what many do not look at when it comes to determining the GOAT is longevity. Unless a QB was to put together something like a 5-year run winning the SB in almost all of those years, which has never happened (except for Bart Starr--different era), it is the fact that Brady and the Pats have managed to do it over such a long period of time. That to me is what gives him the nod. He's almost 40 years old.
GOAT is not just about talent or MVP brilliance. Contrary to what some of you think about him who grade him lower than Peyton Manning, I have a feeling that before his time is up, ARodgers may win the most MVPs of any QB in the history of the game, but if he and the Packers don't win SBs to go with them then it won't put him in the discussion of GOAT.
For now and the foreseeable future, it's Brady.
Oh, and since this thread is about Martellus Bennett. Glad the Packers got him!
