At the risk of giving the OP more credit than he deserves, the only difference I can see in his list is that Georgia is the only team of the four from the East whose rotating cross-division opponent (Arkansas) finished below .500.
But if that was the point he was trying to make, he severely half-a**ed it. Arkansas was the only team from the West who finished below .500. So the OP could have listed all 7 East teams and UGA still would have been the outlier.
