Yes I do realize that. But a MMA guy doesn't focus on striking?
So a person who focuses on striking will be at advantage. Plus his strategy will be to remain in a dominant posistion. Which is standing. So he will use antigrappling techniques and quick escape techniques when he is taking down to get back to his feet. Plus on his back he can also strike. An if he does conditioning such as iron palm,Iron fist,Iron fingers. Then even his strikes on his back can be menacing.
Many MMA come from specialized Striking backgrounds: MT, Kyokushin, Kickboxing.
Silva and GSP have SOME striking skills
If you take a kick boxer who spends most of his training time punching and kicking a heavy bag,punching a wall bag filled with steel shots and Hitting a makiwara board.
First year he strikes 80lb bag
Second year he strikes a 100lb bag
Third year he strikes 200lb bag
Foruth year he strikes a 300lb bag
and Fifth year he strikes a 400 lb bag
(An he can move the 400lb bag with each strike)
Dude...seriously...what are you talking about?
This guy;s punches from the ground are still going to be devasting. Imagine him opening up chain punchs or performing a Chin Na technique on a grappling arm trying to fight for the dominant posisition. Besides no matter how skilled you are in groundfighting you won't be able to defeat every untrained fighter.
His punches will be as devastating as they can be IF he has trained them that way, standing punching ans ground punching are not and never have been the same thing.
For instance lets say you train your son at age three In BJJ by age ten lets say he manages to become a black belt. Do you think your ten or eleven year old son will be able to submit Tommy "Tiny" Lister Jr., Shaquil Oneal or Ving Rhymes. I picked these two because the average Black Belt BJJ guy who are not heavy weights would have hard time fighting these guys with Wrestling techniques. They would fair better with Muay Thai or Boxing. If they have the correct conditioning and power to adminster damage upon contact. These guys to best of my ability have no ground skills. But I bet you in a real fight they would demolished most if not all middle weight and Lightweight BJJ guys. Just my opinion. Not saying they couldn't be demolished.
Size matters LESS in grappling than it does in striking.
It still matters, a GREAT DEAL, anyone that has ever fought full contact with no weight limits knows this.
An in a confrontation of multiple attackers your ground defense would be useless!
The chances of you going to the ground VS multilple attackers is HIGHER than VS just one.

Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
