This will be an exciting action fight. It's gonna be good until it last. Baby Bull will stop Kats on the later rounds.
I don't think Amonsot has a glass jaw. He came in very ill prepared and just got hit with a very well timed and to be honest "lucky" punch in his only other loss. Katsidis was landing bombs and Amonsot never looked like quitting. Diaz will beat Katsidis by out working him, and by using that jab to great effect. Like he did against Cotto, Diaz can box when he needs to, and Katsidis will eat a lot of jabs. In close quarters, Diaz is the better combination puncher but Katsidis has more one punch power as well as the tighter more accurate punchers. I expect Diaz to win by a decent margin, but it will be a war, and Katsidis will get plenty of opportunity to land power punches. He will have to increase his work rate from his last bout if he is to have any hope of coming away with the win. One thing that Diaz needs to do is shorten up those punches. His hooks are quite wide at times, and against Katsidis who stays right on your chest, these will not land effectively.
Amonsot doesn't have a glass jaw (Despite what BoxRec says - And I don't think the KO loss was ever shown, which says a lot about you), and Katsidis won almost every round. Yes, Katsidis got cut badly, but only one was through a punch. That fight was one-sided, although Katsiis' face tells a different story. Katsidis has his faults but is better than most non-Aussie fans think. His lack of skills are covered by his physical attributes. Strength, stamina, power, chin etc.. You can pick his style apart all day, but you could for Foreman too, so lets not judge him too harshly.
man this would be an entertaining fight. I was just thinking about this after the Katsidis Amonsot fight. I think Diaz takes this one. Katsidis would make make him work for it though.
