Every few years they make a deal out of the PTB and the refs start the season pinging guys for the lack of foot usage... Then it drifts away again.
The way I look at it is that it doesn't really effect the game at all if the ball is placed on the ground and rolled backwards.
The actual rule these days is that the foot doesn't have to touch the ball though. You just have to make the effort to make it look like you have, which is stupid anyway
I think the play the ball with the foot rule does matter. Its a fundamental ruck discipline in rugby league . It creates a subtle skill in every ruck and not just a lazy approach. It matters very much. Its an integral part of learning rugby league. It promotes discipline and respect for the games rules en masse. You get that fundamental ruck rule wrong other rules are flaunted as well.
