BIting scratching and eye gougeing really over rated...grappler for these resons.
Just raising some questions:
He's also expecting you to stay in once place or backstep, but usually not to sidestep or jump/dive out of the way.
2 You are trying to keep balanced(if already on ground then trying to not get pinned up)
A lunge is usually an off balance and committed move. The Experienced Grappler (EG) is trained to compensate, but should the target not be in place when the EG gets there, he's got to recover and that takes time.
3 He can do it back to you and since your in his ball park he can do it much more and worse.
Generally NHB/Pride/UFC type fighters train to do legal moves. They can improvise, but they're not trained to do it reflexively. In this it depends more on the individual than the style.
4 you might be giving him a submission by sticking those arms out
True, but a striker is trained to strike quickly and you have to admit, it's hard to catch a non-committed motion, especially if you're trying to seize the limb that's moving. If a seize is missed, it very likely opens up another gouge which my bite harder.
5 A good fighter will not be dazed by Scratching or Biting,
That's like saying a good fighter will not be dazed by seeing his ear in your mouth or will not be dazed by a good gouge to the sac. It depends where the gouge, scratch, or bite is. If you have a death grip with your teeth on a guy's nose, chances are it will faze them. When people see damage to themselves, they panic, especially if they know it has something to do with that greasy wetness pooling where their ear used to be.
6 The eye gouging is hard to do on someone who is shifting around you as you roll.
Realistically, shifting around as you roll is hard to do on pavement, stairs, and uneven ground. Eye gouging penetrates the same holes as punching, which your NHB heros seem to have little trouble doing to each other.
7 Good well rounded grapplers will defend once you do get a eye hook in.
EG's will defend against hits period. Experienced strikers will do the same. But a gouge to the eye will always get their attention. Sometimes it will make them react quicker and turn their fight ON. But others will panic, which I think to generally be the case. It depends on the individual and the framework of the injury. One thing to remember is that if they can't see you, you have a better chance of getting away or attacking them when they can't defend, EG or not.
8 you will be trying to stand or doing somthing else and wont wont to confront a grappler ON THE GROUND.
If you're not an EG, you DON'T want to confront an EG on the ground. That's a fact. Don't fight an enemy where the enemy has the advantage. Grapplers took the fight to the ground, because they didn't want to be in a striking game, where the enemy was strong. It's the same principle, just applied in a different manner. It goes both ways.
True fact, NHB training is for a ring against someone who wants to fight you. That makes the framework of the fight they train for involve two willing combatants. Much less time is spent on capturing somebody who's trying to escape than in trying to fight someone who wants to fight you on the ground. A lot of grapplers will be out of their element if your sole purpose is to escape them and then return the fight to stand up position.
Also, usually public fights involve more than one person on each side. It's always one crew vs another crew. Never forget the guy you're fighting on the ground has friends close by who will kick you and stab you and bludgeon you. Most of the time, they don't even care if they hit their friend accidentally. It's not wise to go to the ground while fighting a guy who has his friends around him.
