There is virtually no realistic trade that will get you anything close to equal value for Prince this season, and maybe not one for Hardy either. I personally think JJ is one of the two guys that you want to build around, even with his struggles this season. I wouldn't put him in an untouchable category, but he's closer than anyone on the team other than Braun. Everyone is hurting for pitching. I'd tend to hold tight and see what hapens this season. They'll need some luck and better performances, but they still ahve a shot at the division even as presently constructed.
