Well if we get Colon, why would we need the Yanks...oh wait, could it be for them to take on some sort of salary.
Yanks get there left fielder in Lee (I thought they'd be happy with Matsui, Mondesi/White, and Williams, but some say they need a leftfielder), Expos take on a bit of salary, Sox get Colon, and Yanks/Expos get some other guys?
I dunno...I'm tired and speculating
