Danny decided to keep two celtics during the course his house cleaning. (Doc and PP) For everything positive Pierce gives you he will eventually do something to take it back. I have tried to rationlize Doc's substitution pattern. I have come to the conclusion it's based on internal team politics. I think the Onus is on Doc, Pierce and Danny. In that order. If this team does not get to the Eastern Conference finals then at the very least two more moves should be made.
