Yes everyone was behind the ball when it was played. This leeds fan either does not understand the rules or is just bitter. My guess is a bit of both.

IIRC Alan Hunte got penalised at CP for being in front of the PTB when Saints kicked downfield on the last tackle, even though he played no part in grounding the Wiganer (Hampson?) with the ball. Botica took the two points on offer. That game ended 8-8 and effectively gave the league trophy to the dirty cheating Pie-eaters as they had a superior points difference.

If you are in front of the PTB you are offside - end of.

Honest question here. How could the refs enforce that, without having a touch judge or marker or something to indicate where the exact 5 m behind the PTB was, similar to what we have with the 'retiring 10 m' thing?

I think that was one of the problems.

Exactly its not a new rule at all. They only lost a game to the Bulls, we lost a championship to this rule.
