Cro Cop was also special forces before/during his MMA career.
For the most part, the guys who seem to struggle are the guys that probably wouldn't have done much without MMA anyway. I see a guy like Leben, and I don't picture him being a big earner in the real world. Best case scenario for a guy like that is trade work. It's not a knock against the guy, because he gave a lot to MMA, and I'm appreciative of that, but not everyone is born business savey.
