Only two of the 11 NFL head coaches hired in 2009 remain: Jim Schwartz and Rex Ryan. Other nine -- nine! -- each now fired.

And each of those teams fans were screaming for a head coaching change too. The problem with coaching changes... once you start, where and when do you stop? how long do you give the new guy?

We only gave Juan Castillo 3/4ths of a season (that had NO offseason to prepare) before wanting his head on a platter...

It's a drug... once you start you can't stop.. and you can never go back ...
