Because that it a totally consistent argument we do with all athletes...allocate much of the credit of a great athlete to life lessons they get to former coaches.
Manning in Denver was due to the lessons from Dungy, right? I’m sure you make the same point about Adam Vinatieri with the Colts, Jimmy Garoppolo with the 49ers, and when a former Patriots player fails in a subsequent role, you’d clarify that it was due to poor lessons on leadership by Bill?
If Brady had fallen on his face in Tampa, would you really be arguing that Bill’s bad lessons and mentorship caused him to fail?
This off-season. the main points were that Brady was helped tremendously by opponent-specific coaching insights, ingeniously tailored game plans, the superior chameleon system, and Bill’s film breakdowns.
Now that those things no longer seem credible, you just move the goalposts to an absurd argument that life lessons along the way - from Belichick - are in any way responsible for Brady’s success in Tampa in way that requires special recognition.
You understand the argument being made is not a simple truism that everyone owes to past influences and teachers. That was not what he was saying, and you’re aware of that.
