JD broke out in 04 despite poor offensive support. Atlanta is a pretty tough place to hit but he managed to put up some impressive numbers. The big key as always is the injury concerns.
He has so much talent that he can be one of the best hitters in baseball and if you watched him last year, he was consistently good. If he can play 140+ games again, I would imagine he will at least be as good as he was in 04. But that is very tough to predict so I have no idea what he will do. I would probably let someone else take him this year.
