He's had PLENTY of problems, and hasn't pitched in a while. He looks like a lost cause right now in terms of a player. He should be focused on getting better.
It's interesting, because on the Marlins' message board, there was somebody posting right after he was drafted mentioning that he had a drug problem, and everybody pretty much dismissed him. You'd think if this guy knew, the Marlins brass should've known and passed on him.
