CLEVELAND, Ohio -- What's the statute of limitations on barbarity?
The late Jack Tatum of the Oakland Raiders liked being called the "Assassin" long after he paralyzed the New England Patriots' Darryl Stingley with a hit.
Former Buffalo Bills offensive lineman Conrad Dobler, notoriously vicious, proudly wrote a book "They Call Me Dirty," in which he conspicuously failed to deny it.
Then there's Greg Williams, the new defensive coordinator of the Cleveland Browns.
He was the actual, recorded voice of the New Orleans Saints' "Bountygate" scandal when he was that team's defensive coordinator.
It was a system, allegedly in place from the Saints' Super Bowl championship season of 2009 through 2011.
