So if you're standing the mark and the ump yells "STAND!" you can't move otherwise it's 50m penalty (despite the instinctiveness of wanting to impede an opponent that's playing on).
In fact, how many times have we previously seen the poor bugger on the mark looking to the ump, waiting for him to call "play on" because the opponent has run off and the ump has been slow to spot it and call it? Happens multiple times per game.
So what will the ump in control be watching? Whether the player on the mark moves laterally? Or whether the player with the ball has moved off his line? I'm sure they won't be able to do both.
In Round 1 the Maggots will be watching us like hawks, ready to whack our blokes that move laterally when on the mark.
Round 1 2018 the Scum kicked five in the first, almost all from 50m frees.
Here we go again.
