This exercise allows you to develop an awareness of running lines and support play, including players holding their depth and communicating. A difficult drill to master but has excellent results in a game by developing the concept of changing direction twice.
This drill develops the decision making process by making the exercise a cyclic drill where there is continuous decision to be made. There is plenty of activity and the opportunity for the players to learn through practice and repetition.
This drill is a great progression from the three v two drill as it creates multiple opportunities for practice of the skill under pressure. Create three or four channels of 30x20 metre dimensions - marked out with poles at each end.
