I trained with a Shorin Ryu guy in Grinnell, IA for a couple years. He was super-hardcore, and the folks he trained with trained very realistically. They would spar full-contact, and they trained for fast KO's.
Anyways, he didn't look like a typical "karate" guy at all. He looked more like a modified kickboxer. He would angle at you until he found an opening and blast you with punches and kicks right down your centerline until you weren't left standing.
The moral to this story is, if you take any TMA and train it in a realistic way, what you are gonna end up with is gonna look a lot like MMA (since this guys neglected his groundwork, he looked more like a kickboxer.)
Take a look at San Da (san shou). A lot of Chinese TMA stylists do it, and it looks pretty much like Muay Thai with lots of good throws. These guys aren't training MT and wrestling. They haven't scrapped their traditional arts. They are just training more realistically in their arts. Everything ends up looking similar, because after all, a punch is a punch and a kick is a kick. There are only so many ways you can manipulate the human body.
I bring this up because everyone is saying that Franklin sucks now that he has gotten beat by a karate dude. I think that Franklin IS as good as his hype, and I think that he is in the same league (or just a step behind) Liddel, Ortiz, Belfort, and Couture. I just think that it is quite possible for this guy Lyoto to be that good.
TMAs + realistic training + live sparring = typical MMA fighter.
