I don't see how he ever returns to coaching.
Williams can't return. Jeff Fisher can try and add him as a linebackers coach or something down the road but even that will be a tough sell. What owner will put up with him.
Bill Polian on SIRIUS NFL RADIO this afternoon went on a 20 min rant that is must-listen. I wish they archived their stuff so I could link it for ya. Going on about saying this stuff cant be tolerated. That when he was in Buffalo if a guy had a "huge play" or made a "impact play" (ie return a punt or kickoff for a TD, sack on 4th down to ice the game...etc) that they would buy the guy theater tickets or gift certificate to a fancy restaurant something like that. It was called a "reward program" and most teams have it. It's "positive" in nature and such. And he went on with saying in 35 years of being in the NFL a "bounty" has only happened twice. Philly with Buddy and now this. That painting every team in the NFL with a broad brush that well they all do it only the Saints got caught isn't true. That every coach, GM, and owner is forced to sign a form at the end of every season saying their team followed the rules to the best of their knowledge and if they get caught lying the punishment is severe. Not a lot of people know about this. He went on and on about how the Saints have tarnished the NFL and the punishment is just. It was a great passionate rant. Not to mention it was dead on the point!
