I want to be able to give him an A...and the turn around from what GT was just a few years ago have been remarkable. He's obviously a great motivator and both the mental and physical toughness of the team has been top tier since Key has taken the job. He's also made some stellar hires and recruiting appears to be continuously improving. The fact that the SEC had to pay or instruct their refs to steal the game against the dwags is, IMNSHO, a point in Key's favor.
That being said, there's still significant room for improvement in consistency and clock management. Also I ding the overall grade a bit when the team seemed to lose focus when the bowl game when the refs started following the same script as the game against the stupid inbred, dumb shit, lying, useless, goddamn pieces of trash over in Earth's enema hole to the east. If they pull that game out, or at least force the refs to keep cheating through the second half instead of imploding, I might bump it up to an A.
As it stands, a high B seems fair.
