Also based on experienced from last year adult size I would like to add to the incapable player rule something like:
A player is ruled incapable if it is closer than 50cm to the ball and no other player is closer than 1.5m to the ball and the player is not actively manipulating the ball or moving towards the ball for more than 30 secs.
The problem is that some teams in the adult sized just walked up to the ball and then stopped without playing so that the other team was prevented from seeing or reaching the ball.
