Thats because Sylvia knocked Ricco out in the stand up, the fight didn't enter the ground once. But Ricco was KTFO plain and simple, over rated fatty.
When Sylvia fights submission specialists he gets owned, Frank Mir, heck Arlovski barely knows submissions and won against him.
But are main topic, Monson .vs. Barnett, Barnett would definitely win. Twice as stronger, better ground skills (Monsons main game), and better submissions and ground and pound.
