I alluded earlier to the Patriot Way being a major contributor to the NE success, and I stand by it. Brady’s first 3 SB seasons he averaged about 210 yards per game.
Brady was a different animal when it comes to obsession with football and continuously getting even better, so no - just like what I acknowledge with Joe Brady/Burrow, I don’t think he needed that mentor after a while. But make no mistake, Brady benefitted from Belichick..
