Your analogy is terrible. All the decisions you cite have no effect on a live ball. If they call play on then call back for a knock on, it doesn’t matter what happened after they called play on, because the game is always coming back to a set piece, negating that play.
In this situation, it completely changed what happened in the play, and crucially the result of that play stood, rather than being negated as in all your other analogies. Rather than put in a second kick, Wighton took the tackle confident in the knowledge that there were 6 more to come.
It’s completely different you f**king simpleton.
