Hurtado would be too much for Katsidis I think. Rapid hand speed and a decent dig as well. The Hurtado who stopped Randall Bailey would do a number on any version of Katsidis.
Hurtado came close to beating Whitaker and was the only fighter to actually outbox a still formidable Whitaker, and also came close to beating top 5 JWW in Tszyu. The win over one of the hardest punching JWW's in history Randall Bailey was an underrated performance aswell. I think based on all those performances Hurtado performed at a higher level, plus the fact he's a smart in an out boxer with very good hand speed. I think style wise Hurtado matches up quite well against the crude Katsidis and should be able to get the W.
Interesting fight and,Michael would have a good chance because Hurtado doesn't have a good chin and gets into exchanges too much. But if Hurtado played it safe he has the speed to outbox Michael.
Hurtado's chin was fine in my opinion given the style of fighter he was. He took everything the legendary puncher Kostya Tszyu could throw at him and got up when others wouldn't until he could offer no more in what was a war of epic proportions. Evan as an Aussie and a fan of Katsidis, he hasn't got enough weapons or power to beat Hurtado. Hurtado was a fabulous fighter.
