Probably because no two incidents are entirely identical and as I said in an earlier post: the ref has one angle of view and a split second to make that decision. There is not another single person in the stadium that has the same angle of view as the ref and he certainly doesn't have the benefit of replay and slo-mo.

I don't think it's usually the more obscure (for want of a better word) laws that people are worried about, though. It's offsides, ball stripping, forward passes and suchlike that tend to end up being talking points.

Hi, James.

44/50 so far. Handovers done me a few times, always thought that fumbles etc on the last meant a handover rather than a scrum.

Again that usually comes back to positioning and the fact that no one man can be in a single position to see everything. That then leads us on to the desired involvement of the TJs.

I agree. It's not knowledge of the rules that's in question, it's why they don't seem to be applied in the same way consistently.

What like Dobsons touchdown against us at the magic weekend.

Never knew you had to restart play with a scrum for a burst ball, even if it's not been spilt. Strange rule.

Another one:

Blue puts a high cross-field kick into the Red in-goal. An on side Blue player leaps for the ball and after gaining possession is tackled by his opposite number whilst still in the air. This causes the Blue player to lose the ball over Red's dead ball line. Your decision is:-

How is this a 20m restart for Red and not a penalty for a tackle in the air?

Finished, 77%.

Just realised this is the one I disagreed with.

Correct defending team can tackle in the air.

more evidence, Briscoe loses the ball surrounded by 3 players, it's a knock on, not a steal...................

Can the experts clarify if the ball has to go past the second row in a scrum to be "out" or not please?
