New Rules 2019

[The_Rookie]

A couple of questions have come up with some officials that I wanted to put on the table here

On Shorts..ok to roll them down at waist. What about players rolling up the bottom of their shorts?

Assistant Coaches can help and come on the floor during a fight without penalty. What about an Athletic Trainer?

Does your area use an uniform Pre-Game timeline? Example get Captains at 4 minutes before tip off..etc.

Preference on having a joint Captains/coaches meeting or Separate with each coach and the Captains?

Thanks!
