You are delusional, and I mean that with no disrespect. Rickson's record in professional fights is 460-0. Show me a single fighter that can even approximate this. If we include amateur brawls, that record rises to 2,000+ wins with no losses.
You seem to ignore that, even to this day, most fights end on the ground, and who's the king there? Are you really that insane that you believe that Fedor would be able to grapple with Rickson once they are on the ground? Fedor has a small chance of knocking him out when they are still standing, but that's his only chance.
If you think that Fedor's greater size and strengh would close the deal, think again. Rickson has fought with Zulu, a giant who outweighted him by 100 lbs, and who could crack the trunk of a small palm tree with his base hands. Strikers, graplers, wrestlers; Rickson has fought with all and defeated them all. Boxers, kung Fu masters, black belt karate champions; all were demolished by Rickson. As for a BJJ black belt having been defeated at MMA, who cares? He was not Rickson. Rickson makes black belts seem like white belts. Like Royce said:"Rickson is ten times better than me. When it comes to him, I am just a fan like everybody else." Or to quote Mirko Filopovic:"Rickson is Zeus, the god of the gods." Just accept the facts that Rickson is the greatest ever, and bow down before crushing greatness when it's staring at you.
Man he has great TD defense.
Sub grappling, BJJ tournaments do not a fight make. Beating Zulu? Come on. Enson Inoue put a beatdown on Zulu, and even though Enson is a friend of mine, he wouldn't exactly compare Zulu to Fedor. Why didn't Rickson fight Saku? Kerr? Plenty of opportunity. He instead chose to fight Takada, twice. A notorious "pro." Takada's resume is as full of holes as Barack Obama's. The only noteworthy Takada ever did was have a dojo that Saku came out of, and he had about as much influence on Saku as Inoki had on Machida. In other words, none. Mas Funaki gave Rickson a decent mouse, what the hell would Fedor have done? Again, I am a Gracie association student, have repped Relson in sub grappling, even rolled with Rickson himself (yes he is a God in subgrappling), but his game has too many holes. Fedor could beat him standing, in the clinch, and unless Rickson got top, Fedor would GNP him into oblivion. Don't think so, watch the two Nog fights. Nog has one of the best closed guards in MMA/NHB. Again, this is not sub grappling. Bud Smith, David Levicki, Gordon Gordeau, Yuki Nakai are all tough guys, but none of them are even in the same league as Fedor.
Counting guys like Larry Hartsell, Hayward Nishioka, Erik Paulson (who was his student at the time), Mark Shultz as wins on one's record is ludicrous. And if that is the case, where is the Ron Tripp "fight" which Rickson lost, but complained that he didn't know the rules. I guess it falls in line with the Stan "The Man" versus Dennis Alexio fight, wherein Alexio gets his leg broken by a roundhouse kick, his manager Bob Wall protests and has it removed because the association Alexio was the champion did not allow round kicks? WTF? Again, this coming from a Gracie student. Stop the blind jockriding and give some honest evaluation of what is real, and not so much. You lost all credibility when you listed Zulu as a landmark fight for Rickson. Hell Rickson's beach battle with Hugo Duarte was more significant.
I'd dare to venture that Ze Mario was the better NHB/MMA fighter than Rickson. At least Ze Mario took on all comers. Renzo is THE FIGHTING GRACIE. He fights anyone, any size, purse nothwistanding.
