The thing is, most good players traded at the deadline are for prospects, not a rental like Kike, unless you find a competing tham with a surplus of RP'ers who is dying to get Kike.
Now, maybe a three way deal, where we give Kike to one team, that team gives prospects to a non-contender, and we get a solid RP'er could be possible, but I think we just trade a prospect or two for a RP'er or two, like we did with Robles & Davis, last season.
