It was speculation, it wasn't unanimous. Brady was being brought up, true...but people would also bring up Terry Bradshaw had a gang of wins too. Statistically, Brady wasn't top 5 anything his first 5-6 years...you just had to bring him up because he won 3 championships.
He just won...not discounting that, but Troy Aikman "just won" too. Statistically Aikman wasn't a beast nor is he top 10 QB's either, but he skirted the conversation because you can't deny 3 superbowl wins.
It was a different conversation prior to Moss. A speculation conversation...People before Moss brought up the Tuck rule and he only won by 3 on the backs of his defense prior to Moss. Once Moss got there, then Welker, then Hernandez and Gronk, people started saying Brady was an undisputed GOAT.
Brady led the NFL in TDs in 2002
In 2005 he was #1 in passing yards
