A simple marker player where the 1st marker moves with the pass from the attacking hooker. The 2nd marker plugs the gap antisipating the hooker running. Once the ball is passed the 2nd marker ties in with the 1st marker and the Open Side A defender and the Blind Side A, B and C defenders much also move up and left to cover the opening made by the 2nd marker. With the aim being a new defensive line closing all potential treats.
