I dont know. Brown had himself a well paying and easy gig with ESPN. I think football coaches are like boxers and cant turn off the adrenaline rush that comes with their respective sports. Same thing with Jon Gruden going back to the NFL and the Raiders after a long stint with ESPN as well. I guess Bill Cowher is resisting the urge to coach again. He seems to enjoy working at CBS.
Brown won’t have the kind of pressure at UNC he had at Texas.
