GREENSBORO — Michael Malone reached the next stage of his transition from coaching NBA players to coaching college players this week when the players on his first North Carolina team began classes. “The school started [Monday],” Malone said. “I was in the NBA for 25 years, and now I’m checking on classes. So, it’s a completely different opportunity, but one that I’m embracing and excited about, and we have a lot of work to do.”
