Clifford added that both those improvements are quite reasonable, since they require effort more than skill.• Add power forward Marvin Williams to the injured list with a right elbow contusion. Gerald Henderson (hamstring strain) continues to be out and Clifford decided to rest center Al Jefferson against the Hawks.

Hairston originally retained Juan Morrow who, it turned out, was not certified as an agent by the players union.• There was no overhead scoreboard at Philips Arena for Monday’s exhibition. The Hawks are replacing their old scoreboard with a 3-D system.
