Well... I guess I'm confused. Why do you have to dislike him to see the prudence in trading him? I love JD as a player and as a signing. I love Byron Buxton as a person and a player. Making decisions about the team shouldn't include those considerations if moving them is better for the team. This article is about being a GM, not a fanboy.
Players age and with age comes increased issues with durability and health. And, yes, he continues to be a health liability just like when we acquired him. (the year in Atlanta off of which we signed him appears to be something of a health fluke)
I make no argument we will be downgrading the position to some degree by trading him. Though, given his health issues and the available options, perhaps not as much as some would like to think.
