In order to be successful at the high school level, we must be able to pass the ball with intent and quality. This video describes three ways to improve pass quality.
A fundamental requirement to improve pass quality (or really any skill aspect in soccer) is "reflective repetition".

When we perform an activity and reflect on it - what worked, what didn't, and why - we are on a path to creating lasting improvements.
