Josh Harrellson preferred people call him the “garbage man” for his suddenly changing role. Boston coach Patrick Chambers had a different idea after Harrellson’s 12-point, 11-rebound performance in Kentucky’s 91-57 win over Boston on Tuesday: mother hen. “I love that kid,” Chambers said postgame. “He does everything that you want a center or a big man to do. He plays ball screens great, he rebounds the basketball, he blocks shots. He’s the mother hen out there.”
