Most of my learning and philosophy regarding coaching basketball was developed after great frustration.
What you specifically teach is what your players will do best.
What does this program/team need this week?
Players who are committed to the team first will find a way to help when things are going bad, they will do whatever it takes. Kids that are more into themselves will not do that. They will take care of themselves and get more individual when things are tough.
Practice to beat the best.
For us to be successful on defense, we must get back and stop the basketball, eliminate easy baskets, keep the ball out of the lane, and bother the shooters.
