I will skip the Jauron jokes and agree that it is hard to win in the NFL, and over the last several years has gotten even harder. The instant replays and internet experts have called everything into question and put every decision under a microscope and out of context in the flow of the game.
On top of that, it has become the No Fun League and almost touch football. While this is good for player health and safety, it creates situations that favor superior athletes to superior scheme all too often. I think part of Belichick's** success is that he plugs in athletes to take advantage of these changes moreso than others. Success has afforded him that luxury though.
Rex tried to do something similar on offense by going smash mouth to avoid the no touching rules, but was surprisingly oblivious on the defensive side of the ball. Maybe Matt Patricia is a bigger asset to the Pats*** than we give him credit for being?
I trust that I used sufficient asterisks.***
