And imo, Bill got his 'legend' status thanks to that once in a lifetime stroke of luck called Tom Brady. Not by his having control.
I'll say this about that, though.
Belichick drafted Brady, and he did so when they already thought they had a franchise QB in Bledsoe.
I can't blame Belichick for his draft failures without also giving him credit for drafting Brady. Yes it was luck, but every other team had an opportunity to get lucky drafting him for 5 rounds and no one else did it.
I also think it would be interesting to see Belichick coach a team with a QB like Dak.
You can say he never won without Brady and that's true, but it's a long way down from Brady to Mac Jones. A QB that is pretty good like Dak is might be enough for Belichick to win with.
We can talk all day about Jerry vs Belichick but the reality is that if Belichick came here he wouldn't have full control or Jerry wouldn't do it. So if he was here it'd be with the same basic structure we have now.
So Belichick plus our drafting prowess plus a good QB and a young Ceedee? Sure, I'd try that.
