Yes - Paul Anthony Pierce MUST retire a Celtic. Plain and simple.
Like 2short mentioned - The Boston Celtics are different than most other organizations. IF he chooses to stay, then he MUST retire in Green.
He went through the Lean Years, the stabbing (even came back to play the ENTIRE 82 game season after that).....he grew up in Green.
Even when faced with the crossroads decision in his career to be traded or stay and wait for Danny to make a big move (Summer of 07), to my recollection Paul Pierce NEVER held the organization for ransom (See Kobe Bryant's very vocal trade demands)...Paul went about it in a different manner.
I'll go even further - unless The Boston Celtics have a knockout, drag-down trade offer in place for either KG or Ray Ray, then THEY TOO should retire as Celtics.
No disrespect to Rondo, because he is assuming leadership here too - but These THREE players have been the cornerstone of our Championship and our success over the last 4-5 years, and Paul has been the Captain of it.
But yeah - I voted YES, here.
