Only if you can someone who can consistently put up 4 WAR/season at SS. And when you find that guy, can you have him work with Castro to hopefully make him that good? (Note: I appreciate the response to a madman talking about dumping Castro, but Castro has never consistently put up 4 WAR seasons) If we're gonna replace Castro, it needs to be a clear better replacement. I think Castro is a 2-3 WAR/season player for the rest of his career, and I don't think that 4 WAR SS is in our system.
