The Washington Redskins planned to interview their defensive coordinator, Gregg Williams, for their vacant head coaching job on Saturday afternoon, according to a Redskins source. Williams is considered the frontrunner for the job. They have also interviewed Tennessee Titans defensive coordinator Jim Schwartz. The Redskins still have not complied with the Rooney Rule, which requires that they interview at least one minority candidate for the job. They plan to interview Colts assistants Jim Caldwell and Ron Meeks, which would put them in compliance with the rule. But they cannot interview the Colts assistants until after their playoffs.
