Uh no. His predecessors had a Pete Carrol led USC and dominant Stanford and even MSU teams. They played teams that had Matt Ryan, Luke Kuechly, Drew Brees, Calvin Johnson etc etc.
Now we play a bunch of crappy ACC teams and lower division teams and lose to anyone that is good. Kelly started with a full cupboard and a bunch of concessions that none of his predecessors ever got. He was so far advantaged over anyone since Lou that its not even a fair comparison.
