Sorry, but I have to disagree -- and can't just let this go.
Muay Thai and BJJ are not "mixed martial arts." They are just two TMA that the majority of MMA'ist consider to be appropriate ingredients for their "mix."
This argument is as silly as the people who think that Long Island Iced Teas will get you super drunk because it has 10 types of liquor in it.
Well, the truth is, if you drink a tall glass of ANY liquor (providing it's not watered down) it is going to get you drunk.
You may like the flavor of a Long Island Iced Tea better than the same glass filled with straight bourbon -- but the alcohol content is the same.
Moreover, because you aren't sticking a splash of soda in it, the tall glass of bourbon may be even STRONGER as it hasn't been diluted with any soda.
MMA artists sometimes remind of this girlfriend I had that liked the sandwhich from Burger King but like McDonald's fries and then had to go to Dairy Queen for a desert.
If that's what it takes to make you happy, and you are getting what you want: great for you! But don't think I can't get everything I want from Steak 'n Shake -- because I CAN and DO.
Likewise, I don't mix my martial arts because the dojang where I train is giving me everything I want and think I need. Of course, some might argue that hapkido IS a pre-packaged mixed martial art, so that might explain it
Maybe I'm just lucky in that I found a "one stop shop" dojang to work out in.
I never assume a MMA'ist can't fight on the street, although I do wonder if those who tape their wrists, for example, (both MMA *and* TMA) aren't setting themselves up for a nasty surprise when they strike someone with an untaped wrist, for example.
It all comes down to who is training hard and well. Heck, even within a single school, you can find some who are scary-effective and others who can't fight their way out of a paper bag.
Final two cents on this:
I think BJJ and Muay Thai are the preferred ingredients for MMA because you can get useable technique in a relatively short time.
How long does it take to teach someone to lift their knee for a strike? Swing an elbow? How many repetitions does it take to make them effective?
How long does it take to teach the guard position? A scoop throw?
Compare that with trying to teach someone a jump spinning heel kick or a sweeping hip throw.
MMA ring fighters don't want to spend 10 years honing techniques: they just want to get in that ring and kick some booty, neh?
So I think their choices are good. And I have no doubt a 2-year MMA student has an advantage over a 2-year TMA student.
But you know who is scarier to me than Chuck Liddell, Matt Hughes or Rich Franklin?
Those old-school hard core Korean grandmasters.
As a black belt, I can see lower ranked belts coming from a mile away when they decide to throw a technique. I actually have to wait sometimes for them to fully commit before countering.
And those grandmasters can see US coming from two miles away.
Props to you young Turks who want to get in the ring right away and prove something to yourself about yourself. I'm not knocking what you are doing since that's what you want to do.
But a guy like me, nearly 40? Injuries take too long to heal. I've played hardball, and it was fun. But now I want to be able to take care of myself when I'm 60.
No thanks: no Muay Thai in my MA; I prefer Korean kicking just fine.
No thanks: no BJJ in my MA; I prefer to get my Judo via Hapkido instead of Brazil.
But thanks for offering. (raises a toast of pure bourbon, neat) Cheers!
