I’ve said it many times - I’d like to move to a place where the bunker is only used for tries, captains challenge (if we keep them) and serious acts of foul play missed by the ref (where it’s a send off).
I’d also say they’re not allowed to use super slow mo, needs to be at full speed, and can only use super zoom for ball grounding. If they can’t see an obvious error in the refs decision, then it goes with the refs call. Gets rid of the howler, and stops the nit picking.
One of my pet hates is when 2 players contest a bomb, one player comes down with it, but then on super slow mo and super zoom, they see it brushed his fingernail a thousandth of a second before the contest, so it gets ruled as a knock on. Forget that, let them compete for the ball, and unless it’s an obvious knock on into the other bloke, then whovever comes down with the ball has won the contest.
