I've long been an advocate for just throwing the ball up/in straight away, rather than waiting 10 seconds for the rucks and 15 midfielders to run to the stoppage. It would reduce congestion and spread the field. Really simple fix that has never been properly raised for reasons unknown.There was no need to bring in any new rules. Just pay holding the ball and incorrect disposal correctly and you will clean up the stoppages/rolling mauls. Easy fixed...
