Not add fuel to the fire but anyone thinking Rivera can't be fired because he received an extension needs to understand that we have no idea what the details of the extension are because they were never disclosed. For all we know, his new contract could state that if he fails to make the playoffs again then he could essentially be let go.
Not saying that is the case but lets also keep in perspective that Marty Schotteinheimer (sp?) was fired after a 14-2 season.... So stranger things have happened.
All that being said, I don't see him being fired this season
