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 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 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.
