yes but it's there for a reason. there has to be some judgement on whether or not they've impacted the situation because otherwise you'd have perfectly legal goals ruled out because one of the attackers was down injured in an offside position, or just doing up their shoelaces
the protocol is simple, hence why every other league manages to execute it better, unfortunately we have severe lack of a) refereeing talent and b) coaching and leadership from the PGMOL
yes there is. the monitor was not used to evaluate whether he
was offside or not, the var official had already decided he was, it was used to evaluate whether he impacted play. simple as.
not going to discuss the correctness of the decision but he checked the monitor because it was a subjective offside. mwepu didn't touch the ball so it was up to the ref to evaluate whether he impacted play or not
