Tim Duncan returned from his knee injury and had 13 points, six rebounds, three assists and five blocks on 6-of-15 shooting in 25 minutes on Wednesday. We're pretty concerned about Duncan's playing time and games played for the second half, as the Spurs carry the league's best record and were rolling without him. And now that he played a game and looked pretty good, this appears to be a good time for owners to try to sell high.
