I think the missing element in a lot of these conversations (and a long-time problem at Tech) is that we put too much expectation on the coach and give the AD a pass. The head football coach should not be driving branding, fundraising, politicking with the hill, media relations, keeping the boosters happy, etc.
C**** came in with a lot of branding and culture ideas. A lot of them were good. But that shouldn't have been taking up his time. The AD and the GTAA should have been handling that so the HFC can focus on football. Yes, the coach has duties that support those functions - appearances, meet and greets with donors, lunches, media appearances, etc. But those should pretty much be: 'Show up at X time, here's your talking points'. Of course, any messaging the coach wants to send for recruiting purposes should be incorporated. But the GTAA should be freeing the coach up to spend every possible minute on football issues.
CPJ wasn't real interested in that nonsense and so, under M-Bob, it just didn't happen. C**** was too concerned with that and, IMHO, it distracted him from doing his real job. (These things are relevant to every other team as well. C**** shouldn't have wasted bandwidth brainstorming branding ideas that the basketball and baseball team adopted. The AD and their staff should be doing this for the whole AA.)
Key has shown, as much as possible through two games, that he can motivate a team, manage a staff, implement a vision. He has a tough nosed no nonsense demeanor. I believe that was one of the two things that made both O'Leary and CPJ successful at Tech. The drive to push the team to work hard and achieve their maximum potential. (Saban also has this attribute.) The other thing that made them both successful was having a great OC.
Long way around to say that (based on limited evidence) I think Key could be a great coach for Tech. But the next AD needs to handle the non-football stuff. The AD/Hill/Donors need to provide the resources to hire a good staff.
