The difference between a punch and this knee is that is a punch canít be construed as a wrestling move. That knee was illegal but not as blatant as a punch, more like a cross face with a wined up. The wrestler could have been trying to break the grip or block the head. Iím not saying what he did was legal. Again I think the refs got it right. You should get over this and get ready for regionals.
And for godís sake I hope youíre not taking to your son about this because you could be costing him a state championship with your weak mental attitude. Trust me, attitude is everything when it come to winning.
