Tyson techniques in MMA = knee to the head.
Seriously, he would dip under punches and his head would be inches away from his opponent's knees. I wouldn't do that too much in MMA if I were you.
have you tried them? haha i use the dip with the hook at the end most people shuffle or sprawl, i roll my shoulders for fakes all the time... i'll admit though as i was faking someone tried to move in but it was nothing a little foot work didn't solve
