He is, but that doesn't mean the Patriots cheating shouldn't be part of the discussion. The 2017 Houston Astros have been absolutely vilified, and it will always be part of their history. Brady should NOT get a pass here, as the Pats systems was much more elaborate, and involved an NFL cover up.

Oh I totally agree. He and Beli-cheat do not get a pass from me. No question they cheated, got a lot of favorable calls from the refs, etc. He also got lucky in some of his Super Bowls and benefitted from poor play calling by his opponents.
Still, I can no longer argue that he isn't the GOAT given the length of time he competed, at his level, and winning with two different teams. We also know that it was Brady, not Beli-cheat, who was more responsible for the Pats success.
