i don't think this was doc's original idea. I'm of the persuasion that Danny's trying to get trade value for Pierce, and has felt that way since before we even got to the playoffs and was confirmed in that notion with our first round exit. Pierce leaves, Garnett will want to leave as well. If both leave, Doc doesn't want to go through the full-blown rebuilding effort. Doc right now is going with whatever management gives him. So if Danny is going full-bore to move on without our old core, and Doc doesn't want to be part of the rebuilding effort, then maybe the LA situation will be amicable for all Boston parties involved.
This starts with what Danny wants. I'm sure if the core came back, Doc's going to be on the bench, no questions asked, and probably his more preferred destination. Doc doesn't want to appear like he's going against the organization.
