I would not call either of these coaches a big success by any means. Both are at schools where they should win big. Neither have won any type of championship as a head coach and one of them coaches in the ACC. Sorry, I'm not impressed with either at this point. Muschamp has not beaten Georgia as a player or coach according to ESPN.
As for CKS I don't know. I think he's a great DC and recruiter. Coaching under CNS is a huge plus, but who knows what he will be like as a head coach? I would love to see him as the head coach at Alabama one day....... after he proves himself as a head football coach. I am not in favor of hiring an assistant coach as our head football coach.
