Simple again, one from each side in the area, if another player contests, free kick. Still no need to nominate.
Overly complex solution to a simple problem.
so in effect it needs a clear area ( an imaginary circle around the umpire) with all other players to stand back.
As Baloo stated there will be frees given when players encroach an imaginary line.
And what of players who are "slow" to get clear the area or claim to be competing.
A free kick because Miles was on the base of the pack and hadnt cleared the ballup area before the ump tossed it up??
This proposal might be workable, but isnt without whiskers.
It needs a rule, whether its the Ant clear area or a u11 nomination rule
