I can see why Lindstrom is out there, since he's due a raise to (by my guess) ~$3M. I don't understand putting Kepp on the block. We don't have a ready replacement on the farm, and he's only due to make ~$3M, which is peanuts for a starting 2B. I'm a big Kepp fan, so I hope his departure would only happen in conjunction with some other move to bring in a superstar or a more long term solution at 2B/SS.
One crazy thought: could Wade have been given marching orders to clear every single dollar he can in order to make a run at Cliff Lee? That's insane, but the reason I bring it up is the continuous rumors of Astros being a darkhorse in the Lee sweepstakes.
