I really don't think you have much of a shot here. You can't even approach him from a positional help angle. Both of you guys are keeping two 1B, two 3B and 2 OF. (why even keep 4 corners BTW?) You can try Albert/Granderson for Howard/Harper or Granderson/Wright for Harper/Headley but my guess is he'll pass. Does Greinke significantly upgrade his 2nd SP keep? If so that might be an angle too but really you are limited here. If you try to send him an extra 1B or 3B in the trade he has no room. You have to send him an OF somehow or he'd be silly to even look. My bet is if this guy trades Harper to anyone (and really why should he?) it will be to diversify his own keep options. Someone who can offer an elite MI has a much better shot IMO.

Cmon Bud, NOW is the time to sack up and force feed an Olympic style drug program down Fehr's fat throat. Save OUR game from these blatant cheaters!
