In the FoP you don't let them get on with it when they are on the ground. There is a slight relaxation of that in in-goal.But why a time limit, please?
In the FoP you let them get on with it. Why should a ref think he should call a halt in goal with all those players around to sort it out?:sad:
Anyway, why do you want a pile of bodies on the ground struggling with the ball?
This often happens in the NFL when there is a fumble, and everybody knows there is a lot of cheating going on at the bottom of the pile while the officials peel players away to find out who has the ball.
