Coach Gregg Popovich said he'll continue to limit Tim Duncan's minutes going forward. Duncan has missed just one full game all year, but he's playing a meager 27.3 minutes per night. "He understands what we're doing," Popovich said. "It's not so much because he's older. I just want him ready for the playoffs." Duncan is averaging career-lows in points (13.9), rebounds (8.4), blocks (1.3) and field-goal percentage (47.8).
