I worked an AAU national tournament a week ago. I recall reading their rule deviations from the Fed (which is what they use as their primary rule set). From the AAU website, Rule IV, Section G. regarding National Tournaments:
1. Players' jerseys must have numbers on both the front and back.
2. Numbers can be 00-99.
3. Minimum size of numbers shall be 2" on the front and 4" on the back.
4. Teams competing in National Championship tournaments must have white and dark jerseys.
5. Home wears White jerseys and Visitor wears Dark jerseys.
6. The top/left team on the schedule shall be the home team and sit on the scorekeepers’ left.
7. The bottom/right team on the schedule shall be the visiting team and sit on the scorekeepers’
right.
8.
Violation of Section G.5. shall be penalized by a two (2) shot administrative technical foul for each illegal jersey. The penalty will be assessed at the time the player with the illegal jersey enters the game.
I'm guessing the national administrator at the game site insisted that it be enforced as written. Before anyone asks:
