Okay, we all know that he is a "troubled" individual, has a temper, etc. However, he has shown some great signs of turning it around. I've picked him up in a keeper and plan on keeping him.
And you know what, he is actually someone to root for. His dad is in jail for murder, he was drafted as a football stud but decided on baseball, and more. Check out this if you want to read more:http://www.minorleagueball.com/2005/10/6/14948/3847
BUT, as far as fantasy is concerned, I've followed him for 4 years now, and he has always been labeled as someone with one of the most impressive baseball skills in the game. I remember Peter Gammons being asked last year who were you most impressed by in Spring Training, and you can guess who he said.
Perhaps moving to Washington, and having a mentor like Dimitri Young will help him hone in on his enormous potential.
I'm a buyer.
