18. Boston Celtics

Record: 15 - 15
Last Week's Rank: 16
Last Week's Results: L vs. Detroit 88-98, (Wed); L @ Chicago 80-89, (Thu); L @ Detroit 81-96, (Sun)

The Celtics have lost three straight, including two to the Pistons. Rajon Rondo had a huge lapse in judgment when he tossed the ball at a ref last night that could cost him a couple games and a hefty fine. They continue to float around .500, but maybe not for long as they have to face Dallas tonight and OKC on Wednesday. With the Knicks recent resurgence and Philly's surprising start, Boston could lose the crown in the Atlantic for the first time in four seasons. —Angel Diaz
