CHICAGO — John Wall was sprawled out on the floor in front of him doing stretching exercises. A.J. Price sat across from him, his soft cast in his lap and a stimulation machine on his broken right hand. Shelvin Mack sat next to him, wearing oversized headphones and checking his cellphone. In the visitors’ locker room at United Center, Garrett Temple sat quietly in front of his stall and glanced around at his teammates, focused on what was about to happen in less than an hour. He was starting for the Wizards at point guard against the Chicago Bulls. Making his task even more difficult was finding out he wouldn’t have leading scorer Jordan Crawford, who sat out the game with a sore left ankle.
