Who advised Rugby to ban tackles above the waist? Alot of these people are hired by the same sport.
On to these rules
You don't see any issue with players putting their heads where the ball carriers are holding the ball?
The rules alone make no sense. You need to limit the speed of the contact OR need to limit ball carriers movements.
It takes a defender to think the ball carrier is going to step left and he goes right for an elbow to the head... this was the reasoning for making under the ball as the contact point
Given the rules drop the allowed tackle height a couple of cms from the top of the shoulders to the armpit, what exactly doesn't make sense?
And try not to claim the rules are changing to waist height in your answer.
