Celtics trade Semih and Luke

Looks like Danny Ainge is getting a little trigger happy. With Perkins now gone and the O'neals injured looks like we don't have a center until Nenad Krstic rendezvous with the team. This is a follow-up to the blockbuster trade of Perkins and Nate earlier. That's two open roster spots so have to figure that Danny is not done yet..
