Use this drill to practice:
A handler, A, starts on the sideline, surrounded by a cup of D1, D2 and D3. Other handlers, B, C and E, are spread across the field. Defensive wings D5 and D6 occupy space along the sides of the field between the disc and offensive threats F and G, while defensive middle D4 guards against potential pop cuts behind the cup. Finally, D7 guards the deep space.
Note that all positions here are simply possibilities; adjustments in position by offence should be matched by defence, and vice versa.
