In the accompanying chat, Kevin Goldstein had this to say: I agree with everything Aaron says about Castro offensively. Defense, not so much. I predict he'll be a third baseman during the last half of this ten year period, and the stolen bases will dwindle. I thought that was interesting given the variety of opinions on his defensive development. Ahead of Betances? Maybe we can rob the Yankees blind and trade them 1 for 1 then.
