Pretty weird all round, the bunker was going to the board with a decision of no try held up, on field asks how the ball came out, video decided it was pushed out by Souths (correct decision IMO from footage) so play on.
Now if in the action of MILF trying to turn over he did ground it instead of it coming out on current form I don't think there is any question they would award it which I think is the core of the issue, the leeway given in goal is way too much. In fact has there even been a case where the ball has been grounded but the refs said it was too long and the tackle was complete?
