I know it's gonna be harder to cheat without a system in place and the NFL not having his back. Might even have to be on his own merits.
I think the Belichick coaching tree thing is underplayed, if anything. Think about it. The Pats have been dominating the NFL for 20 years, going to a Bowl about half the time, and winning the division all but once (I think). No NFL team has ever even sniffed that kind of success for that period of time. And in that time, how many coaches have gone off to experience some semblance of success away from daddy Belichick?
None. Can you explain that? I think their system of cheating with Goodell in their back pocket is at least a sane argument when compared to Belichick being some overlord, surrounded by mediocrity.
McVay made the rest of the NFL look silly this year yet the Pats knew what formation to be in every time. It was like they were in the huddle. Happened the entire playoffs. What a coincidence ...
