http://sports.yahoo.com/mma/news;_ylt=AmrB_fA_XLVhA_sLONREquQ9Eo14?slug=ys-mmanotes082008&prov=yhoo&type=lgns It's this guy http://www.youtube.com/watch?v=SBbV0L0ypns He'd have no problem taking fedor on the ground. But since it's mma...he'd probably get murdered. (although , let's never underestimate them...Afteral Yoshida did will against Silva , Nastula wasn't bad either , Akiyama is a beast)... If it happens...it's gonna be one of the biggest fight in japanese mma history.
See how he does without a gee. He relies too heavily on it. A move like that, he would just be giving up his back standing to Fedor. Step into him and grab a body lock from behind, end up in dominant position.
Fedor is world sombo champ, so what he can execute elite judo throws and newaza. Fedor can, do it all to elite level i would suggest the guy trains to fight mma, then challenges the russian when he has a idea how much tougher mma, is than the gentle art.
