Just read the big SI piece on him (a week old). All in all don't really like the guy...when he's not on a bender (which he was for much of his earlier life), he's all religious and that's how he controls it. I'd rather a guy just man up and get control of his life himself.
Now, none of that has to do with his ability to hit a baseball, he's one of the best at that. But given his situation in 2007, not so sure I can second-guess the Reds' decision to try to get starting pitching for him. That didn't work out for the Reds, but at that time Hamilton's career could have easily been on the edge of crashing and burning like Ryan Leaf's. Rangers rolled the dice and came out winners, for now. The way it goes sometimes.
