They have been right before. I think.
I wonder what his real height and weight are. I think that a couple of years ago they were calling him 6 3, now they are chopping two inches off that. I remember his weight being listed back then around 170 which is skinny even for 6 1 but now he looks like he is below 150, maybe well below.
I believe that O let it slip out, probably to someone like Deadfish, in order to cover up an addiction, perhaps to blow, as he as already admitted to doing blow in his book, and blow users lie about everything, including weight loss. Also, blow users have other addictions for instance tobacco.
