I dont know much about the head taps but I have experienced pinching. One of our wrestlers tried telling the ref at this past weekends tournament that the other wrestler was pinching him and the ref did nothing about it. After the match he went and sat down and just cryed. We had him show us and there were marks all over his back... pinch marks.. blooded spots from the pinches breaking skin and tons of scratches. You wouldnt believe how bad his back was. My question is how did the ref not know?? I think these refs are letting alot of things slide that shouldnt be! How can we train good quality wrestlers when these novice kids are showing our kids other wise on the mat?
