Communication with the Referee.

[Dickie E]

No they don't - so coach the lads to tackle low, and for a team mate to be ready to tackle whover the ball carrier can offload to - if they are carrying the ball your guys cannot be offside - so get in their faces tackle low, and then tackle the reciever if the player offloads - theu will almost certainly mishandle and you have easy turnover ball.

But tackling high simply leads to players breaking tackles.

The laws don't help in this matter. A low tackle will almost invariably result in the ball carrier's team maintaining possession. A high ball & all hit has a good chance of leading to maul turnover.
