If the Dallas Mavericks don't start stringing together several wins real quickly, a lot of them are going to start looking like the bushy-bearded James Harden of the Houston Rockets. Guard O.J. Mayo convinced several of his teammates to not shave until the Mavs' won-loss record climbs to .500. If the Mavericks, who are 21-28, win their next seven games, they'll reach .500 in a Feb. 26 home game against Milwaukee. If they don't go on a run, things could get, well, hairy. "[Mayo] came out of the blue and said, 'Hey, let's grow our beards,''' forward Vince Carter said. "That's easy for me." Coach Rick Carlisle said he's open to any suggestion. "I've heard a little bit about it, and I'm all for it," Carlisle said. "I'm in favor of anything that creates solidarity and a focus on a certain mission, so I like it. No one's approached me about it yet, and I doubt they will."
