Rob,And I agree with the above post that considering wrestling around on the ground to be a waste is pretty ridiculous. There are young, athletic, and somewhat hot-headed mixed martial artists training to move in and take people off of their feet on a daily basis. Not preparing for this, and all of the other ground-related possibilities is what is ridiculous. Plus, regularly wrestling around on the ground with a trained grappler would highly improve the odds and speed of quickly gaining a dominant postition and either striking, breaking, weapon deployment, or simply escaping from your attacker.
You are probably referring to my post. I base it in real life experience. I am small and weak. When I was a kid, I was the target of bullies. I got my ass kicked many times in school fights and mugged. When these fights went to the ground, they killed me with superior size and strength. When I was 12, I started judo and learned a few locks and pressure point moves. One day, while a guy was twisting my head off on the ground, I happened to remember a move my judo instructor had taught me not long before for escaping from a standing headlock: pass your arm around his shoulder and press a finger at the hollow of the throat above the sternum. I did this. It was like pressing the button on your seat belt. Magically, the other guy, who was as usual bigger and stronger, let go. After that, whenever I found myself on the ground with someone, I never wrestled them. I went for the eyes or the throat. I rarely had a problem on the ground. I was usually able to get away (though not always). This experience leads me to question the overall utility of wrestling on the ground in a true fight. You can take it or leave it, whatever your personal martial religion happens to be.
That said, however, I have had the opportunity to work with a BJJ practitioner. I wish I had known some of that stuff when I was a kid. It would have saved me a lot of lumps.
