Will Muschamp, Texas' defensive coordinator and head coach-in-waiting, has turned down a lucrative offer to be Tennessee's new coach, sources close to the situation told ESPN.com. Tennessee athletic director Mike Hamilton continued to work toward having a coach in place by this weekend, and one of the candidates the Vols are zeroing in on now is Duke coach David Cutcliffe, who is a former Tennessee offensive coordinator. Sources told ESPN.com that Cutcliffe has talked with Tennessee officials, although he's not the only candidate the Vols are considering. Air Force's Troy Calhoun and Louisiana Tech's Derek Dooley are two other coaches on Tennessee's list, and the Vols also might be interested in talking to Clemson defensive coordinator Kevin Steele.
