I know what you mean. The head of officals from the travel jr high league I coach was telling all the representives from each youth associatins that there is going to be new rules on hitting from the Illinois High School Association (we use high school rules). I'm sitting their quietly as he is talking and I was thinking to myself: "Dude I got real obvious helmet to helmet shots on tape that your crews missed now you are telling me you really crack down".
I am all for making the game safer. In fact as a defensive coach. My top priority has been to teach kids how to tackle safe and correct. In some recent clinics I have seen tackling technique demonstrations from Wisconsin, Minnesota, and Northwestern. I think though as you alluded to we have to enfore are current rules before we make new rules.
