NFL

I'm guessing because just like his players, he finds the best scheme fits and knows how to get the most out of his players and coaches in the past. Having josh McDaniels for almost all of those Brady years meant that he wasn't constantly losing OCs to HC jobs. Coaching is all about finding the right ppl to mesh with the right players you wanna have around your program. I think he finds good coordinators, but when they try to make the jump to HC it never works. Everyone knows about the Brian Flores Miami situation, but he's now gone to the Vikings as a DC and has turned around their defense. I think Bill creates a lot of positive bias towards people that work for him, And like a lot of players, he does a good job at playing to strengths and hiding weaknesses
