The issue is that there's a difference between "The doctor botched a surgery" and "I know more than the doctor, because I saw something online". That's the difference. We see this in public health today, too many idiots are running around screaming nonsense, because hard earned expertise isn't respected. No one is saying to blindly accept expertise, but you better come with some legit proof that a concept isn't working.
Miami had the #1 offense last year, it is still a **** good unit this year, and that's with Miami having to break in a lot of new, unproven guys in the WR room and at TE. The OL has taken a step back, because Brockermeyer isn't Lee or Carpenter, but he's serviceable. Beck isn't Cam Ward, but there isn't anyone in the country that is Cam.
We have multiple years of proof of concept. As long as the QB isn't a complete moron(TVD), and turns the ball over at a high rate, this system works and can be effective. Is it always pretty? No, but it is simple, and overwhelming to most opponents.
