UNC clinches share of ACC title in one of best coaching jobs of Roy Williams' career Posted Feb 25, 2017 North Carolina knocked off Pitt on Saturday, clinching at least a share of the ACC regular season title. It’s the second straight season and the eighth time in 14 years that Roy Williams can make such a claim. For comparison, Mike Krzyzewski and Duke have won just three ACC regular season titles in those 14 years and they haven’t won one since 2010. (NBC Sports)
