Klay Thompson won't play Saturday night against Brooklyn because of back stiffness that has troubled the Warriors' shooting guard on and off this season. Despite the pain, Thompson has averaged 15.2 points and 4.3 rebounds during the Warriors' franchise-record 10-0 start. "He was a little stiff in shootaround this morning," interim head coach Luke Walton said. "He was getting some treatment afterward. We were going to see if it would loosen up throughout the day, and they just told me 'It hasn't.'"
