Overcoaching in games is never good but coaches should do the following.
- Wait until plays are over before speaking. During the action advice distracts more than helps.
- Have an erasable clipboard available to diagram plays and positioning. Visuals are often much more valuable for learning than just words.
- Have someone take video to analyze later and to show players when they do not seem to grasp what they are doing and to compare to video clips found online of the right way of doing things.
- Continually teach players when they should look to the coach for in-game advice. Doing it too little or too much can lead to inefficiency.
- Teach on the field player to player communication, along with how to communicate and when to do it.
