Given it wasn’t really a type of tackle since the last few years it seems kinda easy. You bear hug, jump and in the air use your body weight to bring the defender down.
As it wasn’t used much before the other rule changes (to the head/neck or lower leg) - I get the issue of ‘old man yelling at grass’. And as a guy who played defense - it sucks.
But it’s like once/game and lead to one injury a week.
