HOUSTON - If the Celtics hope to rebound from the agonizing end to their western odyssey, the first thing they're going to have to do is . . . rebound.

It got ugly out here, even while the Bostonians were losing just one game to par on a 3-4 journey. They allowed their opponents more second chances than Terry Glenn, giving up an average of 13.6 offensive rebounds.

While blowing a 14-point lead in Dallas and a 20-pointer here to end the trip, the Celts yielded 13 pieces of offensive glass to the Mavericks and 17 to the Rockets.
