Fedor Emelianenko is a big man but is he doing jiu jitsu? Some will say he is a practitioner of Sambo (russian style submission wrestling). Others will say he is an mma guy who knocks people out.
Here are some facts about Fedor. He fights between 230 lb and 240 lb which definitely makes him big man. He has 30 wins (knockout 7, submission 16, decision 7). Did you catch that middle stat? 16 wins by submission. If you win over 50 percent of your fights by submission you are a Submission Master.
Fedor Emelianenko is an excellent example of Big Man Jiu Jitsu.
