Ga fan here, Grantham's 2010 season was brutal at Georgia as we were transitioning from a 4-3 base to a 3-4. He didn't turn it around really until the 2012 season and he couldn't stop Bama from rushing all over the strong side of the line in the 2nd half of the SEC championship game.
Also, who will ever forget "Miracle on the planes" in 2013 vs Auburn?
However, in games we were favored in, his defenses usually performed in 2012 and 2013.
We had Grantham as our DC from 2010 - 2013, Aaron Murray was our QB all 4 of those years and he holds the career passing yards record in the SEC. Think about that for a moment. How many yards of offense will mullen have to put up to win big games with Grantham is what it tells me. He'll do just enough to make you think he's a solid DC then you'll have a WTF game on defense, usually in a big game. Kentucky last night reminded me of our game vs SC in week 2 of 2010, they ran the ball all over us and looked like world beaters.
Perhaps he'll gain my attention if he starts closing 5 star talent on the DL and at LB, until then he's a liability for the gators reaching their full potential with Mullen.
