I don't know why he was never really warm on State but I do know .... there is a lot more OM influence in Desoto County than MSU. Also he has gone to a handful of OM games, outside his official visits, with friends and others.
Also, on official visits to OM, they rented luxurious cars, rolled them on the field with his name in lights, drove him around in them and many other things on his official visit. I believe he had a standard visit at MSU... facility tour, uniform photos etc etc. ...not that it would have made any difference.
I'm not defending the guy btw.
