little bully

it's not meant to be "neck wrestling" at all it's meant to be jockeying for control of your opponent so you can land a knee attack. it's more than just neck involved, it's nice to control the head as you may then control the directon of your opponent. but you can clinch the body as well. if you want more info i am happy to write it out, i just didn't know how much info you were looking for. hopefully that explains it better.
