here's the thing about this fight, katsidis isn't much of a boxer and only relies on his pressuring style. i also believe his chin is suspect (casamayor KO) and his power is a little overrated. never has he faced a complete boxer like marquez and it's going to show. in the marquez/diaz II fight, marquez virtually pitched a shutout and i think diaz is a much better boxer than katsidis.
