This is very unfortunate. I sincerely hope otha has a change of heart before tomorrow. However, the university of Tennessee is bigger than any one person. If he feels he belongs elsewhere, so be it. We will be fine with or without him or any other recruit. If Arkansas is where he feels he belongs, why fault him?
I do believe that his mother not taking the trip with him hurt us. As with any boy that age, things are different without your moral compass in tow. They may not have given money or whatever else some would wildly speculate. They would have been able to show some of the party scene though, maybe have some friendly girls show him some love. At 17 you think "hey this is great, must be like this all the time." With mom you see the academics, the facilities, the trophy rooms, and the whole support system. On your own you get the dorm parties, the GA telling you negative things on other schools, the bad influences. Without someone in your ear to help you see past all that, the fun of having that freedom will beat the reality of the situation.
Hopefully otha figures out what really is best for him, and hopefully that is to be a VFL.
