Don't believe this. This might be someone trying to create drama across the NBA field. Essentially this trade would go down if the following occured:
-Pierce all of a sudden doesn't care about his legacy with the Celtics
-Fans boo him out of town (for whatever reason)
-Lakers willing to give up a lot of assets
Lakers aren't even a winner this season, so why would Paul want to go over there, make it to the 2nd round and then flame out? So no, this is not ever going to happen.
Paul stays, thank you very much.
