GOAT: Greatest Of All Time. The commentators always point to those two. However, I think what defines that is which makes the people around him shine, who inspires them to realize their potential, who gives them the confidence to strive for more. I think Brady does that. But then, I have never been a fan of Aaron Rogers. I don't like the comments he makes about other players, such as Farve and Brady. I don't like how he treats some fans of opposing teams. I don't like him in interviews. As much as I never liked Brady (most especially because when he was leaving NE, he didn't even glance in Philadelphia's direction), he has a note of humility when he talks about his career and his achievements. He doesn't hesitate to credit others with their role in putting him in the discussion of GOAT. Philly has never had a QB in that discussion. All their best players, like Reggie White and Fletcher Cox, Brian Dawkins, Jason Peters (cox is the only one still active) were not elevated by the QB. It's not that every QB for the birds were bad, just not trascendant.
Montana, Young, Peyton Manning, Eli Manning.... for whatever reason are never in that discussion.
