Who would win if the one of the best proven fighter Royce Gracie went against the fast kicking Bruce Lee. Kinda a battle between grappling and striking. Royce Gracie has won virtually every match in his fighting career, and Bruce Lee is one tough martial artist. Bruce Lee is one of the fastest fighter ever with a wide array of deadly kicks. He has one of the most devastating kicks at his time. Royce Gracie one just about every match in his life as a true fighter. Correct me if I'm wrong, but Royce Gracie was undefeated in his whole fighting career. Royce Gracie might be man that has beaten them all, but has he really been in the ring with Bruce Lee? Hard call, but I would have to go with Royce Gracie. Just because I think he has been in more matches than Bruce Lee and knows how to beat fighters with Lee's style.
