The sad thing is that the shoulder charge itself is not dangerous. Plenty of great legitimate hits have been put on over the years. However very recently a number of these have become sickenly dangerous and illegal. Looking at that video, most of the recent ones end up not being a shoulder to the head, but an elbow to the head. It's all because of the ridiculous technique that the players are employing now, that involves them jumping to make contant with a player who is generally bent forward in a downward motion. The players only have themselves to blame. Hits like the Inglis one on Dean Young are ridiculous and cannot believe some at the time, tried to argue that one player jumping to hit elbow, arm and shoulder first, an already smaller player who is being taclked and falling.
