No it is not silly. The Crabs will have the most as they have a strong presence in the private schools and always seem to draw good players. Other clubs will have a few here and there. If you dont think parents are taking notice you are sadly mistaken. There will be more as time goes by.
To me this is a youth issue about fairplay in youth sports like the poster above. Even if it is just 2-3 per team besides Crabs. Thats 20-30 % of starting lineup assuming they are starters which they will be be at these younger ages. So no it isnt silly and sure wont be silly when you play the Crabs.
