Roy Williams: time to get tougher on No. 24 Tar Heels Posted Dec 18, 2014 Roy Williams says it's time to get tougher on his team. The No. 24 Tar Heels just haven't looked like one of the favorites in the ACC championship so far, leaving their Hall of Fame coach displeased. Williams said he was harder on his team during Wednesday's practice and will stay that way heading into Saturday's game against No. 12 Ohio State in Chicago. (Associated Press)
