It's not like the Spurs have gotten to this record by overtaxing their best players. This is the deepest rotation Pop has ever had this far into the season, and they've been relatively healthy too. Last year they had to hustle at the end of the season just to make the playoffs. This season all they're going to do is win enough to keep the best record in the league, and they won't kill themselves to do it. Their biggest problem will be getting into a groove once the playoffs roll around so that they're playing well.
