Again, you’re comparing basically one pretty successful year (his first, which he had little impact on other than having the headset) to longer and sustained success. Just about any dope could let Vic Fangio run his once in decade defense and stay out of the way.
Yeah, I mean, I just don't agree with your last sentence at all. It's never easy to win games in the NFL, and talent doesn't do it by itself. No one's just rolling the ball out there.
But obviously, if you're willing to say about his most successful season "he had little impact on it", you and I aren't going to agree here. That just isn't a real thing.
What do you think Belichick - rightfully considered the GOAT - 's record is without Tom Brady? Does the fact that he had Tom Brady for the huge majority of his career lessen his quality to you? It doesn't to me.
