I don't really buy the "he could have been rehabbing" argument. I mean, guys can't work out (especially after surgery) 24-7. He's got down time like everyone else, and rather than drinking and gambling, he's exploring his business horizons. I can't blame him for that.
Now, if there was evidence that he's blowing off rehab to concentrate on business, that's another thing entirely. However, until I hear to the contrary, I'm going to assume that there's room for both things in his life.
