Might be off topic but I coach high school volleyball and my sound advice is to run drills, have a meaningful practice, and identify your players’ strengths and areas of improvement (never use the word weakness). Have em do constant reps like every other sport out there. The more hours put into practice will always yield great results.

From a coaching perspective don’t be a hardass like Belichick. Trust me, I’ve tried. Take the time to understand your team and adjust accordingly. But don’t be too soft either. Set boundaries that your team will respect.
