Really? And by club dynamics you mean refusing to play seond base for MOST LIKELY NO MORE THAN ONE INNING, and by doing so decreasing your teams chance to win.
Personally I don't mind this trade because I don't see the Sox re-signing him at the end of the year.
Mueller will probably want a 3 year deal, he's a third baseman, getting on in age, with bad knees, that is not a combination that I want on my team for the next three years.
We have a perfectly fine replacement in Youks and our bullpen definitly needs the help, I think the trade is a good idea. I trust in Theo and his moves. And anyone who tries to argue that the Kim deal was a bust should be reminded, that Kim was a HUGE part in getting the Sox into the playoffs in 2003, ending the whole "who's the closer?" issue.
