Dallas would be a dumb decision. No real GM in place to partner with, so he'd be getting fed players by the owner who of course leaves room for blame to go only one direction when they come up short. Dallas is a circus. So I hope he ends up there.
If I'm him I'd be looking hard at that Panthers job, with the Colts and Titans as secondary options. All those teams have solid rosters and just need a decision maker to sort the QB spot and tie it all together.
Still think he will end up with the Seahawks if they boot Petey, because irritating asshole fits so well up there.
