MB and Tom,
That's not entirely true. I trained mixed martial arts most of my life, from wrestling and ju jitsu to multiple striking styles. Grappling has the advantage once you get a hold of someone, but a good striker doesn't allow you to get a hold of them. Granted, most strikers aren't good against grapplers, because they have only trained with other strikers, but if you watch any MMA tournaments (like UFC or Pride) you'll see a much better balance. Back in the day of Royce Gracie, grappling was king, but since then, strikers have learned that they have to study the ways of their opponent in order to have a chance.
The biggest disadvantage this guy will have in a real fight is size. Being that gymnastic, he's obviously very small. I'd put him at about 5'6" and 135# tops. He'd probably kick the snot out of most guys his size, but he just wouldn't stand a chance against a 275# bouncer. I don't care what they show you in movies, size DOES matter. Why do you think there are weight classes in all fighting sports?
That said, I wish I could flip around like that!!!!![]()
