1. Enforcement of uniform rules:
Some Liberos are not wearing a shirt that is in clear contrast and distinct from other members of the team.
Uniforms are without a front number
Players are removing uniform parts while in the playing area.
Sleeves not the same color as the uniform top
Undergarments that are not the same color as the dominant color of the uniform bottom.
Giving warning to correct instead of enforcing
2. Awareness of Libero situations

Liberos serving for more than one player.
3. R1 responsibilities
