Tim Duncan put on a clinic in a win over the Mavericks on Thursday, scoring 28 points with 19 boards, two assists and one block in 36 minutes. He rested the second half of a back-to-back set on Tuesday and needless to say he looked like an All-Star in the win. It was just the second time since January 12 that he played at least 36 minutes. The Spurs have three more back-to-back sets on the season with their next one coming up on March 31. Coach Pop could still sit Duncan even in a game that isn't in a back-to-back set, too.
