Yeah, Pierce is almost ready to retire anyway. It's sad if a top 10 Celtic doesn't even get to decide where he's going to retire.
I don't think he's anywhere near ready to retire - same draft class as Kobe and Nowitzki, still going as strong relative to those guys as he ever did. He can easily start for the remainder of his contract. The fans will be very very pissed if he is traded, I think, even if it makes sense for the team to do so.
As I said, it is indeed time to blow it up - I just didn't expect to see Pierce's name on the block, or not at this early stage at least (Allen and KG will be let go on July 1 anyway, so it makes sense for them to be the first ones shopped). Pierce has stuck with the team throughout rebuilding before, as much as any player in the Cs history in fact. I think he'd rather do that again rather than go for a coattails championship but I may just be projecting.
