Will Michael Katsidis go farther in boxing than Gatti did?

Nah, I don't think so.

regardless of how long he fights bet damn sure i will be watching drinking some brews

I don't think so, Gatti had pretty good natural talent but most of the time decided to go to war instead, by the time he actually started boxing instead of going to war, he was past it. I haven't seen that kind of natural talent in Katsidis and his longevity in the sport won't be long if he keeps taking the kind of shots that he takes. Pretty sure you have been proven right Silencers.

katsidis lacks any defence.

Good points ,,,,,, Gatti from pre Ivan Robinson was quite a good boxer , I think his heart was just to much the fighter ,,, Katsidis dont have the boxing ability early Gatti had just that same type of do or die attitude , probably 5 yrs tops maybe as little as 3 with the wars he is getting himself into . I also didn't see Gatti run straight in, head first as much as katsidis does either. Most fighters like Katsidis have very short careers. Which I'm predicting....
