Ok lets look at some things during Royce's most dominant stage. First of all no time limits, the Gi was allowed, no stand ups, instead of fighting in pancrase where the best mma fighters were his family created a orginization and invited very few really trained mma fighters and most fighters didn't even know what a triangle choke was. The fact that he beat multiple fighters who all outweighed him in single nights is very impressive and he can be thanked for bringing the sport to where it is today. He was a great submission fighter, tough as nails and a true pioneer of the sport, but I don't think he'd make it in my top 20 best MMA fightes of all time.
