A few reasons. He is still young and can learn new things, and still has a ton of potential. Any fighter with power can be dangerous. Yes, he lost, and was humiliated, but he lost to the best in the division, and he didn't suffer a KO. If he gets his heart back in the game, and takes a year{couple of fights} to work on his fundamentals, he will still be top 5 in the division. Let's just hope he actually works towards being great, and not underachieving as a power puncher=David Tua.
