Don't be sarcastic with your players because you will lose them in February.
Use the cadence of your voice as a tool. Change your instruction.
Kids want consistency. Eliminate gray areas.
Reinforce positive behavior.
You become a master coach when you get away from your practice plan. Have 3 things in practice you warm up with that you want to accomplish.
The more things you try to do in practice, the worse you get. Exercise: Write out your practice plan three times. Each time, don't add anything but remove something.
Look at your methodology of teaching and evaluate it. Don't just worry about drills and plays.
Don't change your system when you lose...change your behaviors in practice.
