Okay, I will share something that will perhaps show some perspective on some things that involve real fighting.
My background is karate originally 3yrs. I now train wing chun and taiji. I pretty much just train CMA now. A while back ago (about a year or maybe even more) I was getting really into my wing chun and wanted to test it out. I knew a guy who did BJJ and had several years of it. He was naturally a real aggressive guy too. I sparred him, and the first time we fought I got my A$$ kicked. I didn't know how to handle ground stuff and since we were friends I did not use any hard knees and elbows and throat grabs etc. Which in turn limited me and I got owned pretty much.
Here is the thing about fighting. There is ring fighting with rules and regulations and weight classes etc etc. There is real fighting that has no rules. I was not about to toss an elbow to my friends head, that has too high risk or a bad injury on him. Many times when he would shoot me (its a take down move he kept referring to) I had some opportunities to attack him as he came in. Whether or not these attacks would be very effective I am not totally sure of because I did not try them, but I have confidence that ina real situation it would hurt someone badly.
After fighting him a while I started to be able to adapt and it was harder for him to take me down. On my feet I was way quicker than him and my hand techniques were superior to his (thats what I train).
In the end I kinda came to the conclusion that there is no long range fighting (kicking) there is no trapping range, there is no clench, there is no grappling, there is no ground fighting, there is only fighting.
Its all fighting no matter what range or position you are in. So I just train to fight now in all situations. I apply what I know when its necessary and what I don't know I learn from experience from sparring others.
However, you must also realize in sparring I dont do any neck chops, elbows to the head, finger jabs, or grab flesh. In a real fight I would have no problem doing this if I needed to.
The key is to just train and build attributes and do not be scared to face it. Have confidence in your style and technique and do not be affraid to get hit you can't always control the situation and you can't always block what comes in at you. Don't be affraid of grapplers they are not invincible and they feel pain. Unless they are uber tough, but then again those guys are hard to beat reguardless of how they fight. I may not be the best ground fighter out there (I mean fighter) but I can definately handle myself a lot better.
In a real fight situation IMHO, ground fighting is kind of pointless. I have not seen a one on one fight since grade school, its always been mutliple people vs multiple people and in those situations I would rather be on my feet.
