>>[truefan] They are ok as long as coaches didn't work with more than 3 players at a time with the ball.<<

Completely ignorant question: what does that mean? In other words, can a HS coach have 15 players on the field but have a 10-yard spacing between a group of 3 who have a ball to whom he's speaking and a larger group doing other ball control work with whom he is not speaking?
