Re: anything like ali\frazier 3?
MMA fights tend to be quite 'cagey', both guys are afraid to commit because it doesn't take much to get knocked out with the tiny gloves. There are a few though, mostly in the lower weight classes though because they don't hit as hard, Chan Sung Jung vs Leonard Garcia I was really good. Horrible technique but a good exciting brawl.
Maynard vs Edgar II was also great, I haven't seen the 3rd one yet but I hear it was good too. Obviously these aren't up to par with Ali-Frazier for me anyway but that is probably a little bias on my part.
