Youth football is about children learning hard lessons that they will need when they grow up to be men. ANY block at or below the knee is something that has a higher rate of causing a serious injury.

A coach that teaches that block is not thinking about the children. He is only rehashing his probable failure as a youth player or ego driven success. There is no reason to continue to allow that block on either side of the ball Chop blocking is not legal in any level of football. Cut blocking is inexplicably allowed at higher levels, however.
