"The Yankees are trying to get Oakland's Mark Kotsay, who can be a free agent at the end of the year. But whether or not Brian Cashman will give up the prospects needed to get one of the game's premier center fielders, like right-hander Philip Hughes and perhaps third baseman Eric Duncan, remains to be seen. Cashman has talked to a number of general managers, but isn't offering to break up the team as some have suggested. Getting Kotsay would completely change their outfield defense and give them a solid leadoff hitter as they try to move Tony Womack."

I dont think getting rid of Kotsay would neccesarily be a bad thing, but not for what is mentioned above.  I would hope if BB is concidering this, we would get some big league talent in return.
