DURHAM — The familiar No. 2 was back in Cameron Indoor Stadium but in an unfamiliar uniform. After three trips and two wins wearing Carolina blue, senior guard Caleb Love wore a dark-blue Arizona uniform with red trim Friday night. Despite some of the heat he got last season from UNC fans, he reminded the world of his love for UNC by scrawling “Tar Heel 4L” (Tar Heel for life) on one shoe that featured a light-blue Swoosh.
