God love you for the work you do, but the characterization of Rick Barnes/Tennessee as unwilling donors and participants isn't really necessary unless you are aware of a similar lack of willingness in all other charity work. A failure to provide an equal amount of attention and contribution to your particular charity of choice doesn't necessarily make him/them selfish, unwilling, uncaring, etc.
Praise Muss all you want for his work and willingness to be actively involved in your charity. I'm glad he is there and willing to help out. But you'd probably defend him tooth and nail if the American Red Cross, St. Jude, or UNICEF chastised him for not making a similar effort for their work. I'd bet there are numerous organizations in Tennessee/CRB's corner, as well, despite you not being a big fan of their participation level in the work you do.
