Exactly what I have said. The strategies put in place to speed up the game are being countermanded by the ridiculous tactics, which let's be real about this , are being employed by players under instructions from their coaches. The constant stop start and let's go back and look at this 50 times to see if there was actual contact to the head is doing nothing to make the game more entertaining nor 100% lessen the impact of concussions etc.
I am not a fan of Andrew Johns but he pretty much summed it up in saying that players are 100% aware that they could suffer a concussion at any time in the game and in any manner ( not just high contact but heavy defensive work by them, hitting the hip of an opponent in making a tackle, hitting their head on the ground or simply by the movement of their heads back and forth in a whiplash type collision) He also went on to say that any player contemplating legal action for such injuries being suffered over their career and the effects afterwards should take a good hard look at themselves.
