And Belichick has never had to decide on whether he should cut Brady a year early or late yet. Really is a whole different scenario.This ain't jettisoning some decent LG or even a pro-bowl LB like Jamie Collins. These two share probably the rarest combination of longevity and success in the history of the sport.
More than anything I think Brady would just call it a career before ever making Bill make that decision. He's been so balls to the wall about this game for so long now, and he's such a seemingly self-aware guy, that he may just decide one day that he's given all someone can to be great for himself and a franchise and ultimately just have the counterintuitive sense to simply be able to turn it off and make it easy for his HC.
Agreed 100% though, it'll be incredibly interesting to watch.
