Here's a tremendous article about Justin Upton by ESPN.
If you read the article, does it change your views on Upton in any way?
I've been advocate for keeping Upton, since I believe that the thumb injury he sustained messed with the mechanics of his swing, but he's been more patient at the plate (just look at his BB%). As I said before, they only trade I would make for Upton would be for Rangers 3B Mike Olt, and a middle infielder. But that's it.
