1. Fedor 2. Minotauro 3. Werdum 4.? Prime CC beat the following fighters: Fujita 2x, Sakuraba, Herring, Igor, Waterman, A. Emelianenko, Randleman, Coleman, Yoshida, Minowa, HW Wanderlei and Barnett 3x. With this winning resume he had the record: 21-4-2. Losing to Minotauro, Randleman, Fedor and Hunt BTW. I don't think fighters with under 20 fights deserve to be in the discussion here.
