Full Field Zig Zag Passing drill
What a great drill to have players catch and pick up ground balls at different angles and at different distances. This is also a great drill for when you are vastly outnumbered as a coach as you can have many balls going at once.
You can even incorporate ground balls as well if the players are having difficulty making the passes.
This can be done on a full field to really work on those longer passes. If need be it can be modified to half field.
