So, could it be Monte? Seems a little long in the tooth to me..
Kiffin has a great track record, even given his age, and time away from the NFL, which is a slight concern for me. But the "Tampa 2" which Kiffin was responsible for popularizing, has become almost a dinosaur in recent years. A couple of teams still use it with varying degrees of success, but there are reasons it has fallen out of favor. Might as well find an Ernie Stautner and bring back the Flex.
I think Kiffin is much better than just a system guy, so I don't discount it at all. But you really need someone who is always adjusting to the game and to his personnel and making the system a product of the talent, rather than forcing players into a system. I hate system guys.
