Paul Pierce thought of leaving Boston after Miami loss
Pierce was unsure of where the Celtics were going after that loss, since Ray and KG were free agents. He also mentions the trade rumors circulating around him and how he didn't want to be part of a rebuilding process. Who could blame him for that.
Also of note is how he mentions he would want to stay with the Celtics after he's done playing, either as a coach or in management.
