Why should you be able to punch the ball ten rows back to waste time?
Personally I think the rushed behind rules and tightening of interpretation of what is deliberate out of bounds have been great for the game. It keeps the ball in play and requires guys to use their skill rather than get a cheap out. I'd rather see the ball in play as much as possible.
But it doesn't waste time because "time on" is blown by the Umpire in charge.
Imo it's another silly suggestion
