Most of the Spurs have grown weary of the travel the team has done this month. Of the Spurs' seven trips in December, only one is longer than a single game. As soon as they unpack, it's time to pack again.
The Spurs begin another back-to-back tonight against Milwaukee. Wednesday's game in New York will be their fourth in five days. It might not be a coincidence that Duncan's 20-20 game against the Clippers came after two days of rest.
"He's not Superman," said one NBA scout, who has watched the Spurs many times in recent weeks. "It's a long season, and maybe he's got it on cruise control a little bit.
"He doesn't catch any breaks at all, either. The superstars all demand double-teams, and people are physical with him. They beat him up and foul him, especially with his free-throw problems."
