If the right deal comes along, I want the Celtics to trade Ray, Pierce, KG or Rondo. Just not this season.

My loyalty is, first and foremost, to the Celtics, not the players on the team.
There´s this story where Danny told Red he would´ve traded Bird and McHale, and in hindsight, that would´ve been the right move.
I´m as big a Ray Allen fan as there is, he was my favourite player in the league since I saw his first game, I love and respect Pierce for everything he did for this team. But, you can´t stop time, and if it´s the right thing to trade one of these guys, I´m all for it. This is not the 80ies anymore, cap and trade restrictions (and the increased athleticism in the NBA) force you to trade players whose salary doesn´t reflect their impact on the court, otherwise you´ll dig your own hole. I don´t want another decade of 20-win seasons because we were too romantic.
That said, I still believe in this core, and I think they deserve -
at least - one more season together.
