Griffin will do well to get a job again.
Cutler doesn't give a fuck, if he plays again it will be for some half decent team on his own terms.
Shannahan might coax him into playing if they offer $$$ but it isn't going to happen really. The man has over $100m earned, he is hardly stuck for a paycheck.
McNair is probably the son of a clansman so I don't think they would consider Kaep. BOB would only ruin him anyway.
