Oh I forgot, you said "no one has submitted AA", no one has even got a judges decision against Fedor! 6 (T)KOs, 10 Submissions, 7 Unanamous Decisions. His only loss was an illegal elbow that cut him and because of the "rules" a winner had to be named, he avenged that decision by destroying him at a later date.
Oh, did you see the World Sambo Combat Championships last year? I'll save you the trouble of looking it up....Fedor won...BIG TIME! His last 2 fights were 14-0 and 12-0 when he subbed his victim.
