Said it early on....its on the Sox and Dodgers to recover this deal. I don't see other interested parties having much impact here. One unfortunate consequence of this mess is that if the actual trade particulars are accurate, everybody knows what the Sox and Dodgers were willing to do. I don't see how that plays to the Sox advantage. I still think this will end up being something the Sox and Dodgers work out. However, the Sox really don't have much leverage here.
On the bright side, players on teams have become somewhat minimally important. They play for the MLBPA now.
All by way of saying that in the old days the deal blowing up and the Sox having to take Mookie and Price back would have had some impact on the players involved. Mookie will go out and try to have a great year regardless of where he is. Price for his part might just be mouthier than normal in the press, alternately mouthing off and going silent enough to be his normal bound to be a jerk self.
It should not take much to get this done assuming both sides are still amenable. I have little doubt the Sox want to do this deal and I have little doubt that the Dodgers want to do the deal as well.
