If the team is struggling at the deadline, if someone gets hurt (or doesn't get healthy), they're bouncing around under .500 and on the fringe of making the playoffs, I could maybe see Ray Allen getting moved. I know Chicago's got Rip Hamilton at the 2-guard spot now, but wouldn't Ray Allen be a perfect fit for them? I don't think there would be a lot in return, but if Danny could pick up a young guy or a pick and not take on any salary past year-end, I think he'd do it.
Paul Pierce isn't being traded unless he asks for it. They want Pierce to be around for the next thirty years. They want him to come to home games in 2020 and get a standing ovation. They want him to stay as the representation of this wonderful era. Unless he asks to go, I think they let him retire a Celtic.
KG, I don't see him having any trade value. Any team that would want him to be that one last guy isn't going to be able to take on his salary. Danny's not going to take a bad contract back in exchange, either. I think he retires after this season (hasn't he already said that was his plan), but I don't think he gets traded.
Rondo, they'll hold onto, at least for now. Might get traded next off-season, but this is his year to prove that his shoulders are broad enough to support the franchise.
