Level 7 Referee
For me it's about balancing probabilities and importance for that scenarioYes, I was also thinking about this. I wonder if this could become the standard instruction.
It’s like the opposite of corner positioning, where the AR starts on the goal line then moves to the second last defender.
Starting level with the 18 yard box puts the focus on preventing encroachment but... well, two buts, not being level with ball/second def and not being close to the goal line in case of goal/no goal when the ball gets played in the goal area... hmm
Goal not goal: most important, probability is minute (given the ball has to touch two ppl)
Offside: mid importance, probability very unlikely
Encroachment: low importance, probability, some likelihood
I'd go with the one that has the likelihood of happening.
