If we decide to keep Fielder right now and don't even try to deal him or listen to offers, I think that's a mistake. Melvin would likely go hard after Greinke with prospects as everyone has mentioned, but I'm not so sure he'd succeed in doing that. If he doesn't, we'd then be sitting here to start the season with virtually the same team, and be completely screwed. Then we'd have to try to trade Fielder at the deadline anyway, and we'd have pretty much no leverage, so we likely wouldn't get as much as we want in return. If we were guaranteed to get Greinke, then I'm all for it. Since we aren't I think we're better off trading Fielder for pitching at this point, because we have no chance to resign him. Keeping Fielder will make no difference at all if we can't find any pitching. It just makes no sense to me really.
