Nobody likes it when the old boss hangs around the hoop causing trouble. I’m no Carolina fan (I went to Duke, after all), but I do feel a tad bit sorry for Hubert Davis, the first-year coach of the U.N.C. Men’s basketball team, whenever the television camera pans over to Roy Williams, the legendary old coach, sitting a few rows behind the U.N.C. bench, scowling or joking around or, you know, passing judgment on how well his successor is or is not doing in real time. (Good luck to Coach K’s successor, Jon Scheyer, who takes over next year while his predecessor enjoys a lifetime contract at Duke and keeps his office in the Schwartz-Butters Athletic Center.)
