Are you serious? Just because some coaches may encourage stalling does not make it right.The worst argument you can make is that the ref cost a kid a match by calling stalling....the kid would cost himself the match by not taking the stall warning serious and fixing the rule violation he is engaged in. It is nothing like taking a knee in football one is within the rules of the sport while the other is a clear violation. Good consistent stalling calls are not just good for the sport they are essential.
