nice matchup make the fight. I give the edge to Rios. Katsidis lost last night because he doesnt have a good enought right hand to try and neutralixe Marquez' left hand. Marquez is not even that fast to be landing cleanly with 4-5 punches at a time with just his left hand. Katsidid solely relies on his left. Reminded me of Trinidad desperately trying to land his left on Hopkins. Rios will mdefeat Katsidis.
As much as I'd like Katsidis to win, Rios would demolish him. Rios more aggressive, bigger puncher, and likes to throw solid hooks and uppercuts. Katsidis would have to be physical with the naturally bigger man. Rios ate tremendous punches from Peterson that would of dropped lesser men, I'm guessing Rios has a set of whiskers too.
