So how was Hooper the top test rugby pilferer in 2013?
The fact of the matter is this Spewn. When the team makes a dominant tackle, if you are a 7 coming across to the breakdown running the correct, most efficient line to get there first, you merely need to side step over the breakdown to make a pilfer, whilst your opposition player needs to double back around to go through the gate, because the location of contact he was running to is now 1 meter in front of where the breakdown has ended up due to a dominant tackle. That gives you the advantage. Otherwise you are relying on poor support to give you the opportunity. Less of those come when the team is getting over the gain line on you.
The other way is the tackle, up and pilfer combo, but that relies on poor support, which is a factor out of your control.
