Chael Sonnen ranks Fedor Emelianenko as greatest MMA heavyweight

Who is greatest heavyweight in mixed martial arts history?
It is a debate that has never truly been settled.For years it was considered Fedor Emelianenko, whose reign of terror lasted 28 fights over 10 years. Others will point to Fabricio Werdum, the man who eventually solved the mystery surrounding the Russian. Yet still, with names like Stipe Miocic, Alistair Overeem and Antônio Rodrigo Nogueira floating out there, the argument continues on.
But for Chael Sonnen, the answer is easy.
