The AP reports: Paul Pierce spent part of the week looking over the schedule, counting the missed opportunities that cost the Celtics a chance to repeat as the No. 1 seed in the Eastern Conference. There was a loss to the Clippers in Los Angeles. Another to the Trail Blazers when Brandon Roy was out… Pierce scored 21 of his 28 points in the second half, including the go-ahead free throws with 97 seconds left to help the Celtics earn their sixth straight win… Rajon Rondo had seven points, 10 rebounds and 12 assists for Boston, and Glen “Big Baby” Davis scored 22 points with eight rebounds. Dwyane Wade scored 21 of his 31 points in the second half, adding nine assists, to help the Heat tie it 95-all with just under 2 minutes left. But Boston scored the next eight points to pull away.
