HWs generally aren't too good on their backs, because of their weight and gravity, but there were some who said: "F*ck gravity." 1. Werdum (it reached mythical levels) 2. Minotauro (prime Minotauro's guard was sick and he had the chin to make it impossible to beat him there) 3. Fedor (In his prime, he was less active then Werdum and Minotauro, but he knew what he was doing and was great at conserving energy, defending and evading attacks and exploding at the right time to escape, reverse or submit people) 4. Mir (great submissions, but worse defense than Fedor) 5. Funaki (34 career submissions, many vs great fighters, I rank him at 5, because he didn't have to deal with closed fisted GNP and great wrestlers) 6. Bas (Incredibly for a fighter who had 15 wins via submission, Rutten never attempted a single takedown in his entire career. Clearly, "El Guapo" had a unique and extremely effective style. attempted a record 53 submissions and successfully swept his opponents a record 46 times) 7. Suzuki (21 submission wins, Suzuki has been praised many times by elite fighters such as Josh Barnett, Bas Rutten, and Ken Shamrock for his outstanding grappling and submission skills) 8. Barnett (20 submission wins, very good of his back for a big guy) 9. Monson (ADCC great, I don't think I need to add much, he isn't higher, because he is more a top guy) 10. CC (prime CC had an awesome defensive guard, I would rate him higher, but he has no subs from his back) Honorable mentions: Cain (impressed me vs Brock). Oliynyk (41 submission wins of all kinds, but the competition doesn't allow me to put him higher), Yoshida (very good of his back, used his gi a lot though) What do you guys think?
