Could just be a Rooney Rule, could be legit. He was a well respected player by all accounts and certainly you have to admit the Belichick coaching tree in college is pretty successful when you factor in Saban, Ferentz, and Pat Hill did/are doing plus early tenured NFL coaches like Vrabel, Judge, and Flores. Everyone thinks about Weiss and Crennel and maybe even McDaniels, but those aren't his only coaches. Guy has churned out as many good ones as bad ones. That's not at all to say Mayo should be considered or is ready to be a HC at all, but I don't think the Belichick coaching stigma is universal. I think Belichick's system and style translate well to college, I think the biggest reason it works in the NFL is because guys respect Belichick whereas its hard to implement that type of culture elsewhere when you don't have his resume. Patricia had no respect to back up his tough talk and culture BS, so guys rejected it. I don't think college kids reject it as easily.
