Is that a punch?

I've just add a clip of fight between Luis Fabiano and Diogo..well yeah this isnt MMA fights..of course their quality of fighting is a "bit" low. They throw some punches but none are landed (except the first one)....

Well punch need to have accurate point , speed and strength. You dont need to throw punches...just throw a punch with a good speed, accuracy and strength..
as you may see in fight between Cro Cop vs Bob Sapp
