Roy Williams: Tar Heels have 'no idea' of Tennessee's toughness Posted Dec 14, 2017 Roy Williams said on his weekly radio show that he’s issued a warning to his seventh-ranked Tar Heels heading into Sunday’s game at 20th-ranked Tennessee. Williams said he told his team it had “no idea” what kind of team it was going to face Sunday, and what kind of environment to expect in Knoxville. The Vols have already beaten Purdue and two ACC teams. (247 Sports)
