Not to defend Fisher too much, but Les Snead didn't exactly give him a team that was expected to have positive results. Besides Gurley, their offense is terrible. Thinking back to a lot of Fisher's teams, I never thought they were the best, including the Titans that lost in the SB.
I agree that he shouldn't have had so many chances after many losing seasons, but would you honestly expect a coach (not named Bill) to win more games with the same teams?
