CHAPEL HILL — North Carolina hadn’t had a game like this in a while – one in which coach Roy Williams could give his reserves significant playing time and experiment with different lineups without much thought or worry about the final score.

Days after playing what’s likely to be remembered as one of their most difficult games of the season, the Tar Heels on Tuesday night played what could be remembered as one of their easiest – a 97-48 victory against Evansville in which UNC built a 30-point halftime lead.
