That may be true, but both have their own disadvantages, too. Using a FB telegraphs where you are going with the ball, and taking snaps under center means you lose precious seconds when you pass (during the 3-7 step drops). Plus the QB has his back turned to the defense on a play-action.
I understand what you mean with the taking snaps under center thing, but you have to try it, IMO. If you can successfully run some stuff while using a FB as your lead block, whether that be off tackle or between them, then you can be truly deadly with our weapons on the outside. Bray's biggest problem is his ability to make accurate reads and throws with a rush coming down in his face.
I think this team is capable of having successful play action with Bray under center, but Chaney just bails on it too fast. That's just my opinion. Against Florida, who has a great DL, I thought Neal ran very effectively between the tackles. I also think if you let this OL go out and really give them an honest chance to smash it in there with straight power, they can be successful. But if you just bail on it and the majority of the passes you run successfully are out of the gun, you become predictable. I think that has been Chaney's biggest problem, he is just very predictable as a play caller. It's not like I am offering a groundbreaking point by saying that, as many have already said the same thing, but I think it's pretty obvious. You have to keep digging.
I think that's what makes UGA good with run game. Even if they have some short gains and stuffs, they stay with it and don't give up. Chaney just gives up when things get tense. And I think that feeling just gets passed through to the players when they feel like their OC is just giving up on something.
EDIT: And, to me, Bray hasn't proven anything. He has a unbelievable ability to wing it and make strong throws, but his pre-snap reads and his decision making after the snap are not good at all, IMO. I don't think he has the mental game to play QB at a higher level than what he is at right now. If you are in your 3rd year of the same system and you can't even be trusted to make reads at the line by your coaching staff, then there is a problem. I feel very confident in saying Bray will not be an NFL QB. Someone will draft him because of his potential, but I just don't think he's got the head for it. And after hearing all ******n offseason from Dooley about how mature he was and how his reads were so much better, that has just seemed to be a bunch of BS to me.
