The college game has been influencing the pro game for a couple of decades now, and I think Bill didn't keep up. Mobile quarterbacks, pass-happy offenses, and defenses built to counteract that. Bill's reliance on big, plodding linebackers and inability/neglecting to add athletes on offense was his undoing. UNC basically has no quarterback as Bill didn't address the position in the portal and has a staff full of guys who have the same antiquated thinking as him. Sprinkle in the blowup doll with direct football staff access and a book tour, and it really seems like at best, Bill lost his fastball, and at worst, he is mailing it in.
