I simply think that he thought he had his mind made up and then wavered after it was too late to cancel. I don't think he is the type person to cause people to waste their time and money to hear him say nothing.

Maybe he was coming back and his family said "what about us and your brother?" or maybe he was going to go pro and Saban talked to him about commitment and loyalty or maybe he was just being a wishy washy kid. All understandable. Wavering is surely a better reason than having all those people there on the company dime to hear nothing.
