Doc Rivers said Chris Wilcox needs to raise his game "in a big way" as the primary backup behind Kevin Garnett. "Whatever number you want to put more (that he has to do), use it," he said. "But he has to, and I've told him that. It's no secret. We're down on bigs, and he has to play better." "He definitely put a lot on me, and at the end of the day we all have to respond," Wilcox said. "I just go out, play hard and bring energy."
