Anyways, preserving mediocrity for the sake of stability is insanity. Stability only matters when your preserving success. The only way the Dolphins start beating the Patriots is to build a talented team. The way to do that? Have a talented and skilled general manager. It starts at the top.
And before people start in, yes: some teams have done what the Texans have done and kept their regime intact despite limited success. In those extremely few cases its fairly obvious the team is talented and they need to take make a few adjustments. Yet how about the teams that keep their regimes intact a year longer than they should? It happens almost every offseason. This year it was the Chargers and the Bills. Last year it was the Dolphins and Tony Sparano. Eric Mangini's Browns. Wade Phillips Cowboys. Etc, etc, etc.
