He's a football coach. Getting fired goes with the territory and should be expected. I don't think he meant it that he hated his other positions, after all much of his staff came from Georgia Tech and Miami, etc. Although, it could be construed that he was taking a shot at Kansas City, Tech, Miami, Dallas, Denver, or whatever.
FWIW, I think he'll be employed again soon enough. And, he did wring blood out of a turnip on offense.
