Superfan

NFHS

During warm-ups 2 participants of the home team had different colored uniforms than the rest of the players (18 total participating in warm-ups) It was obvious their basketball skill level was not as good as the rest of the team and they spent most of their time rebounding and throwing the ball to other players and just having a good time.
I had a chance to ask one of them in warm ups if he knew they all had to wear the same uniform. At that point he said: Oh, I'm not a player, I'm just the "super fan" and won't be participating in the game.

Anybody heard of this? Is it legal? They were having way to good of a time for me to tell them they couldn't warm up with the team.
