If Beane is going to trade Harden, he's going to want Harden's replacement in the deal, ie Sean Gallagher, and then a couple of good upside players, who are close to being MLers themselves, perhaps Pie and Ceda? Not necessarily because he could bring up Gio Gonzalez. Beane would probably want to wait until the very end of the trade deadline to give Gonzalez a few more weeks in AAA. If Beane feels the time is right to trade Harden, Gonzalez is just about ready and as a young pitcher he'll benefit from McAfee Stadium.
