Despite Gruden's chummy persona on TV, he's reported to be an abrasive schmuck behind the scenes. And not the 'Tough, gets people motivated' type, the 'What an ***hat, I can't wait to leave this team' type.
He ran a better offense than Dungy. Not a difficult thing, Dungy's offense was Parcells without the innovation and risk taking.
Going after Gruden is a Snyder-esque move -- oooh, a shiny name that I recognize! It would actually be far more of an indictment of JJ than staying the course. Anyway, the signing of Kiffen pretty much nixes that deal, if those numerous reports are to be believed.
