And it's not irrelevant because of the precedent. For lateral moves, you have stuff like Randy Winn or the two Florida prospects going back in return. For promotions, you have Andy MacPhail going for a random A baller. Plus in this case you have the Cubs taking on a significant financial obligation for Theo that they don't have to. Bingo. Actually, precedents are irrelevant until a mediator steps in. Of course Boston is going to ask for the moon, regardless of any promotion Epstein may be getting. And of course the Cubs are going to compensate for what they deem is fair value, since Epstein is under contract with Boston for another year. Both sides are seeing that "fair value" quite differently. Look at it this way: Seattle didn't take Randy Winn for Lou Piniella because of any precedent--they took him because they felt it was a fair trade. The Twins didn't take a Low A pitcher because of precedent, either. They did what they felt was in their best interests. Right now, the two sides are attempting to reach this fair value on their own. But if they can't, either Boston walks away (highly unlikely), the Cubs walk away (also highly unlikely) or a mediator steps in (which is becoming increasingly likely, though both sides would have to agree to a mediator AND abide by the decision that mediator comes to).
