Royce was larger than Saku (taller). Renzo is similarly sized, as is Ryan. Conan was much larger (not a Gracie, but part of Carlson's team), Ebenezer Braga is similarly sized, and although a Lutra Livre fighter, he is a member of Gracie Barra. Rickson, if he could get the fight to the ground would have had a DEFINITIVE advantage. Saku's wrestling was so good, and if it were to go to the ground, Saku would be in top position and probably sit in Rickson's guard knees to elbows and await the stand up. Altough his standup isn't anything to write home about, Saku is better than Rickson here. So even match, whomever can dictate where the fight takes place mostly wins. BTW, the rumors of Rickson's ground abilities are grossly UNDERESTIMATED. I attended a seminar years ago, and as is customary, he rolled with everyone there and submitted everyone within 3 minutes. Over 85+ rolled with him including Egan and Enson Inoue.
