Remember '78. to most people we are NOT hiring a Head Football Coach. We are hiring an offensive football coach. The other 200 facets of football don;t seem to matter to most. Of course I am kidding, but it does seem like that sometimes.
Your take on Norvell is interesting and somewhat reminds me of Brian Kelly after his first year at ND. Now I am certainly not equating ND to Memphis but your mention of defense strikes my memory. Kelly had a successful run at Cincy and was known as a good offensive mind. But after his first year at ND I think they finished near or just above .500 including a bowl game. They asked Kelly what were his priorities in the offseason and the first thing he said was "I have to go out and recruit for defense" He then said "I can manufacture offense, but I can't manufacture defense" . I think Shane Matthews has gone on record as saying if you are an offensive minded coach and take over a porous offensive team, that results and improvement should almost be seen immediately, even if not by huge strides. But it does seem that ND's most successful seasons since Kelly has been there has been when they have been athletic and talented on defense. This year they are not dynamic on offense and have a limited passing game, but they sure are physical, possess the ball and run the ball with incredible effectiveness.
