Basketball guys can sure be little people at times.Duke assistant coach Chris Carrawell refused to shake the hand of UNC head coach Hubert Davis in the postgame line.Notice that another Duke assistant who also played for the Blue Devils, Nolan Smith, appeared to purposefully look away as Davis approached (although they did shake hands).Davis, a former UNC player who played more than a dozen seasons in the NBA, told The News & Observer he didn’t understand Carrawell’s snub.“I don’t know what that’s about,” Davis said. “I didn’t play against him, I don’t know him personally.”But Carrawell told the newspaper it was revenge after Davis “did not shake our hands before the game.”However, the N&O noted that before the game, Davis was not yet on the sideline when Duke’s staff entered Cameron Indoor Stadium at the time the coaches usually exchange pregame handshakes. However, he and Coach K did shake hands prior to the start.At least no coach threw a punch, like Michigan’s Juwan Howard did recently in the handshake line after losing to Wisconsin. He was suspended for the rest of the regular season.
