Katsidis is a gladiator. Popo was a beast in his prime. Popo overpowers and drops Katsidis several times, but Katsidis would bravely fight back and would probably score one of his own. Popo by late tko and leaves Katsidis a bloody mess.
I would have love to see this fight. A war to the end. I'm edging towards Freitas because of his great skill and speed, and the fact that he showed a lot of heart in his fight against Barrios and Casamayor.
