In fairness to the ref, Professional players are at fault here ; they go to ground for no better reason than to seal the ball off. Others will stand as pillars, with no opposition players contesting the ball. They and their coaches have created the "non-ruck", so perhaps they might acknowledge that fact, before slagging-off the referee's attempt's (on prime-time TV) to take split second décisions, about these situations, that don't even exist in the lawbook.
Munster's inexperienced coach said:
"“BJ’s thing is a point of law. If there’s no ruck formed, which there wasn’t, ...
Whose fault is that Mister Foley? not the referee's, surely? Try asking your pros to respect the laws of the game.
If players are not encouraged to stay on their feet, & contest the ball, then the Lawbook as it stands is of little use.
Rugby is a contest, Pro players are ruining the game, by working around a loosely written lawbook.
Either rewrite it gentlemen, or Feck off and play soccer!
Pillars at a non-ruck are offside & must retire 5m/10m, for example.
