Is it possible that Bronco went from a 26 yr old meat head jock to a more mature, more composed head coach which generally comes with a self driven expectation to be an example of self control?
The Bronco people often bring up was a young guy not all that far removed from his playing days in a coordinator role. Head coaches don’t have to act like a maniac with coordinators and position coaches up and down the sideline around them.
I don’t think there was some conspiracy to change or muzzle Bronco or otherwise he would have eventually evolved back into his “true personality” by now after 2 seasons at Virginia which he has not.
