Nice Quiz, I felt I basically only remembered the big names. Is it possible you did not include some fighters in the quiz by accident? I felt there were 2 or 3 names which the quiz did not accept. I think "Chiesa" was one of them but I do not remember for sure.
Anyways, nice one, thanks.
EDIT: "Chiesa" works, I just rechecked it but I think one or two other names did not work, but maybe I made a mistake and typed in some strikeforce fighters who never fought in the UFC.
