Sorry if this is a re... didn't see anything.. Now, I know that there isn't a sole winner to this one but this question is often asked and I kind of see it like this. U.S.A. Japan Brazil Those three are the big MMA countries and all seem to produce champions and very strong fighters of all weight classes. Funny thing is possibly the greatest welterweight ever is Canadian...French Canadian at that but are there more Canadians even worth mentioning? (forgive me if that sounds rude) Russia possibly has the GOAT. - Any others that are consistent? I'm tired and just got home from the gym so I'm done.. lol.. Any thoughts?
