Rays will surely continue to try and trade him, but I am guessing that the previous asking price will need to go down. It's not that I think they are asking for more than he's worth, but rather that I figure he would've been traded already to some of the other teams if the return they were looking for was less. From what I've read, most discussions involving a Price trade were initiated by the Rays with them basically saying "we'll give you Price if you give us prospects X, Y, and Z."
I would guess that the best teams to trade for him are Seattle, Chicago Cubs, and the Diamondbacks. Seattle definitely has the pieces to get it done but I think they are smarter to hold on to them. Cubs probably make a lot of sense as a good fit for him, and they've got a healthy farm. Diamondbacks are the ones I hope to pull the trigger. Kevin Towers will surely trade away everyone they have to get that trade done, and then they can have a Cy Young candidate for 2 seasons, no future, and a shitty farm. This would make me happy, even if it meant having to stomach Price own the Dodgers' lineup multiple times a year.
