I have a 13 year old whom has been wrestling for 7 years and is a 2 X state champ. He also plays football and his new coach teaches the players that when they tackle they grab above the waste. In fact he gets so upset when the players grab for the legs for a tackle that he makes them do extra running. In wrestling when you take down your opponent you always go for the legs. And the lower the better. Now my question is so when tackling in football do you wrap the upper body or the legs?
