In my opinion it has to be Fedor Emelianenko.. His skills are unparalleled!! I might entertain the thought of some people saying Anderson Silva. Anyway, What is your opinion??
I would say Anderson Silva because I have actually seen his fights. If I have seen Fedor's fights my opinion may be different though. I can not really form an opinion on Fedor because I have not seen all of his fights. There are so many great fighters out there right now any day this could change!
