James Michael McAdoo and Reggie Bullock are learning how to be go-to guys. Their freshmen teammates are adjusting to college. And coach Roy Williams is waiting for his players to hit some free throws. It's clear 11th-ranked North Carolina has plenty to figure out heading into a demanding five-game stretch. McAdoo had 19 points and 11 rebounds to help the Tar Heels beat Florida Atlantic 80-56 on Sunday, earning a second win to build some confidence before heading across the country and visiting the nation's top-ranked team in the coming weeks.
