teaching zone

1) get 7 players who know how to play zone
2) get your team together
3) if they know how to throw and catch well, play agressor squad vs new players
4) if they are new players... use a red kickball and let the players throw the ball around so that they can have completions. If they need to, just let them throw it around... and bounces are cool.
5) Use a teaching technique called 'freeze and discuss.' where you let the play develop then call freeze. then discuss positional issues. use this as an opportunity to move people around.

To develop speed, incorporate this workout in the early season: not the late season.
run laps around the field: run the diagonols at a dead run with good form. then jog the endzone. Repeat for 20 t 30 min. Note. This is an early season workout. Not a late season workout. This is to develop form, and develop conditioning. Focus on form.

Then, 10 minutes of throwing. Focus on crisp throws, imagining a mark... Alternatively, 10 minutes of mark drill. College kids, do this now, and you will improve.
