So for those of you hoping that somehow Holliday would end up in our outfield...oh well.  This could be the first domino to fall, though, in a series of moves over the next couple weeks.  If I had to guess, the Athletics will be sending some combination of Daric Barton, Travis Buck, Gio Gonzalez, Dallas Braden, and maybe even our old friends Sean Gallagher, E-Patt, and Murton.  I'm sure they'd love to ditch Crosby, but considering the Rockies already are saddled with Tulowitzki (who's still salvageable) and Barmes (not so much), I doubt he's involved.  but we'll see..
