So now Bill Belichek is an offensive genius? I'm surprised considering his history as a Defensive Coordinator.
I know, it's crazy, right?
Here's how it prlly goes down: Beli, the D guy, breaks down the other team's D, finding tendencies and weaknesses, perhaps w an assist from analytics. THEN, he forms a "pow wow" with the OC and Brady and discusses the best way to attack the other team's D, which, low and behold, involves his input as to potential play selection. Weird, right? THEN, in the game he is in the loop when Brady and crew are on the field and if he sees something the defense is doing he QUICK, makes his thoughts known as to what play(s) may work there and then--he may even take executive action and call the dadgum play hisself. And dadgummit if he ain't real good at that. I know, right? ERGO, vicariously, Beli could be considered and prlly IS an "offensive genius".
It's kinda like when an ex QB is coaching safeties or something. Football's weird like that.
Hope that clears things up.
(p.s. Beli + chick = Belichick)
