I'd actually prefer that Richt go after an up and comer QB coach/game planner from a spread coaching tree. If Richt is calling plays, i think it would be beneficial for him to bring in someone who is maybe 2 years away from being a full fledged OC and who brings in a slightly different offensive philosophy. A mutually beneficial relationship, where Richt helps prepare the guy to call plays and the guy helps push Richt in his play calling and game planning. I don't have time to look up names, but I'm sure there are quite a few names out there that would be worth looking at.
I think the one thing that leads to complacency and eventual failure, is surrounding yourself with all like minded people who fall in line. I believe that's why Al Golden has already reached the pinnacle of his career, because he refuses to be open to doing things any other way but his own. If your going to act like the smartest man in the room, you better **** sure be it because eventually everyone is going to learn the truth. You need people around you who think differently than you and you have to be open to their ideas, in order to maximize your own abilities.
Saban's hiring of Kiffin is a perfect example of that. I would have never thought those two would be coaching together, because they have different philosophies and clashing personalities. But Saban realized he wasn't going to win games 10-6 anymore and that he was going to have to start winning games 33-28 and 45-41. So he brought in someone to open up the offense a bit, while still wanting to control the game by running the football.
