Dude looks like he's about 4'8. He will never get any respect. He's making at most 300k per fight. As someone who is as dedicated and as hard working as he is, I don't doubt that he could be making more money if he actually decided to venture into some other business.
The perks of being an mma fighter is the respect, the recognition, and the money. He will not receive any of these 3 being in the flyweight division. On the other hand, he gets everything bad that comes with being an mma fighter, such as body breakdown and getting punched in the face. Should DJ become a software engineer instead?
