Tackling

When tackling in rugby, the player making the tackle should be low with his shoulder leading into the tackle.  Unlike a football tackle where your head is across the body, your head needs to be behind the body you are tackling, otherwise the person will throw their knees and potentially knock you out from the impact to your head.  When you tackle, you need to take the man down to the ground all the way otherwise it is an unsafe hit and potentially a yellow card.  After you take the man to the ground, you need to roll away from the tackle so your team can set up a ruck.
