Tim Duncan (rest) will be back in the lineup Monday against the Sixers. Gregg Popovich sat Duncan in the second half of a back-to-back Saturday as Pop attempts to keep his 36-year-old forward fresh. "I'll be ready to go if he allows me to play," Duncan said of Monday's game. "So I'll show up and see what he says." Duncan also said he doesn't even try to disagree with his coach. "I never fight him," he said. "You lose every time."
