With the new year came a new identity for North Carolina, one that has caused fits for Atlantic Coast Conference opponents.The Tar Heels (12-6, 5-1 ACC) have won four straight, holding each opponent to a lower point total than the previous with a stout defense to stay near the top of the conference standings.”I desperately want them to see and experience what this team will look like,” UNC coach Hubert Davis said. “If we fully commit to becoming the best defensive team, rebounding team and taking care of the basketball.”UNC will need that defensive prowess on Saturday when it hosts Stanford in Chapel Hill, N.C.The Cardinal (11-6, 3-3) are led by Wooden Award contender Maxime Raynaud, who ranks 10th in the nation with 20.5 points per game and third with 11.5 rebounds entering Friday.Raynaud comes off a season-low-tying 14 points in Wednesday’s 80-67 loss at Wake Forest, but Stanford coach Kyle Smith said the 7-foot-1 forward’s decision-making “is getting really complete” as he serves as the Cardinal’s quarterback on the floor.”That stuff he’s starting to figure out, and he’s starting to let the game come to him a little more,” said Smith, whose team has lost four of its last six games. “That’s dangerous, because his skill set’s ridiculous, and now his feel’s starting to evolve.”
