Since Brady is a FA and let's say he doesn't stay in NE could Belichik be lured away?
IMO both scenarios, are extremely unlikely. Brady, play for another team and completely different system and coach at 43 years old? Unless the Patriots don't want to resign him, I don't see that happening.
Belichick is not only the coach, but I think he's pretty much the De Facto GM. See the problem there?
