Facing that is a stack of 8 cutters and defenders at least 20m away. Take turns cutting and defending. The cutter cuts toward the thrower, trying to get free from the defender to receive a pass. Note that there is no marker so it should be easy for the cutter to get free eventually. The receiver takes the disc and joins the throwing stack.
Variations Have the person who is second in the throwing line put a mark on the thrower.
One defender may mark the disc, the other tries to anticipate and intercept passes. The thrower may not pass to the people directly next to them. The receivers may not move to catch the disc. After three turnovers, new defenders are chosen and the old defenders join the circle. With more players of a higher skill, put three defenders in the centre and practice zone defence.
