Or perhaps you're referring to modern Pancrase--a competitive format derived from professional wrestling? :huh
Beach wrestling was a very good call, whoever said it. As for me I would have to go with Luta Livre from Brazil which has produced one of the best 145lb fighters in the world in Alexandre "pequeno" Franca Nogueira, can't believe nobody has mentioned this, as I really don't think it counts as catch wrestling or jiujitsu. Beach Wrestling Shotokan Karate from a good school, which has produced several good fighters, Lyoto Machida being one that pops into mind And if I can use it without it being considered to close to modern boxing, London Prize Ring Rules style Boxing
I said it, however I just moved on as I figured that people weren't familiar with it. I also said the obvious kickboxing, which wasn't listed as one that couldn't be used. Shoot wrestling, shootfighting, or shooto would also be good calls.
What type of specific striking defence disciplines would be the major, for people with glass chins like Liddell, they specifically need it.:think
Mendoza's boxing system would be best. The closest thing to a bareknuckle boxing wrestler's stance--extended arms to catch punches early, a solid base to prevent takedowns, and a few nasty holds to pummel a guy inside. Also, the base is suitable for modern boxing footwork and especially head movement. Heck, the arms are even well placed to wrap around a guy for Thai clinching. Defensive MMA fighter's dream style, except that the legs are probably too wide and thus vulnerable to a good leg-kicker.
Krav Maga -- haven't trained it. I hear that most branches of it in the US are not legitimate, but I imagine military-affiliated stuff would be. Crav Magma -- I've been training it for years, honing my body to diamond-hard consistency in the volcanoes of Hawaii.
You have got to be ****ing kidding me.:huh He's been KO'd one time, by a damn hard looping right hand that connected right on the button, and now has a glass chin after a career of being known for having a pretty damn good chin? People are so ignorant and fickle.:verysad
Dirty boxing is nice, as you can clinch your opponent and manhandle him a bit while hitting. If you keep your opponent off balance, and on the defense, he isn't likely to catch you with a big punch. Also, how about the crazy ****** style? Liddell himself is a Kenpo (Kempo) fighter, and that wasn't listed either. Seems to suit him just fine. BTW, I don't see how he has a glass jaw. I think that Liddell's chin has proven very good in the past.
