I thought Wandy is due to be a free agent after this year. I also thought there was talks to sign him long-term, but I never heard that it was actually done. If he didn't get extended and Wade then expects him to bolt after this year, I understand the trade talk. Otherwise, I don't get it.
Assuming he is traded, I'd expect much more than some middling prospects for him. IMO, Wandy has consistently been an above average starter the last three years or so. That is valuable. The thing I read somewhere speculated the going price would be a below-average big leaguer, a lower level pitching prospect, and a reliever prospect. Fuck that, that's a bunch of nothing for a hard to replace commodity.
