I think Brady wanted to leave the Pats just to distance himself from Belichick. To show the world that it wasn’t just them as a pair, that he could do what he does sans Belichick.............
I would agree with that, but Brady had all those years with Belichick, and the apprentice became the master. Had it been a different team, a different coach who knows if Brady would of endured as long as he did or been able to achieve the records he did. Brady had good teams around him for most of his years.
