"If your mind can handle it, your body definitely can," forward Jimmy Butler said before the Bulls defeated the Knicks 93-85 Saturday night at the United Center to end such a stretch. "If you're telling your mind, 'My body's not tired, my body's not tired,' then your body's not going to be tired. It's a mental factor."
