Rodolfo vieira, undefeated with 7-0. He's the most accomplished BJJ artist to ever step foot in the octagon. Even surpassing Werdum and Jacare.
And unlike other BJJ fighter, Vieira actually has pretty good takedown. And he's very big for the weight class, quite a lot bigger than izzy. which matters a lot in the wrestling department. if Vieira took Izzy down one time, the fight is almost guaranteed over.
