Wrestling techniques are very effective for No-Gi Submission Grappling. Head Control is an important ingredient to setting up and completing techniques. It is also important for defense. If you are in control of your opponent then he cannot be in control of you.
The main thing with Wrestling tekks for No-Gi competition is you have to protect your neck. If you shoot in for a double without disrupting your opponent's balance and your head is hanging off to the side you may be giving them the Guillotine. Good head control and awareness can help prevent that.
