now he'll have to work a lot harder coaching at UNC than he did at Texas, but that could literally be said for any coach (Saban, Meyer, etc..) that went to UNC from a major stop.
He's not going to win any NCs at UNC (who would) but he will have them playing better real quick and once he gets talent in he is going to be good enough to be quite the pain in the ass for everyone who used to be able to just chalk them up as a W when the schedules came out.
