Either way, it was disastrous timing no matter what occurred. In hindsight it would have been better to appoint Kippy as interim, but that's only because they selected Kiffin. Remember we could have had other guys back then other than Kiffin, namely Sumlin. Sumlin wouldn't have set the world on fire here, but we would have been much better off hiring him than Kiffin.
The architect of the downfall of Tennessee athletics, particularly football, is Mike Hamilton. Ultimately the people who hired Hamilton (admin) are to blame.
