This is a great drill to get players building a progression starting with a 1v1, then a 2v2, to a 3v3 and then to a 4v4. The drill starts with a 1v1 in the corner and it is simply mano to mano. Offense is focused on beating the defender and going to goal. The defender is working on solid 1v1 fundamentals. After the shot/goal/turnover, a second twosome enters and the offense can work on the 2 man game while the defense needs to communicate and work through picks. A third twosome is added and offense can work on spacing and ball movement while defense can work on help and slides. Finally the fourth twosome joins into a 4v4 situation. At the completion, the field empties and the sequence starts over.
