VAR helps, but i think its clear that even with VAR replay, people still dont agree with all of the decisions, so much is down to subjectiveness(is that a word?).
True. Take yesterday's "elbow to the jaw" incident for instance, cheek of the defender rippled and swirled into ringlets when seen in the zoomed replay. It looked like one of those Rocky slow-mo sequences; yet, ref still gave only a yellow.
Emotions running high, being flocked by screaming players, stadium going wild, score being tied and you're faced with giving a RC to CR, Ballon d'Or candidate and top flava of the week. Easy to get overwhelmed.
Ref would need a set of heavy cojones to make that kind'a call. That dude did for instance during the Remontada but then he got investigated and couldn't officiate for 6 months. So there's also the fear of that...
One solution could be to entrust the decision to a panel of judges having access to multi-angle zoom slow-mos, from the comfort of an AC cooled lounge, rather than have the ref run to the pit-side monitor to review the sequences.
First, it would save time and easier for 3 judges to make tough calls. 3 or 5... As long as it's an odd number, majority wins it. 2nd, would make no sense for the players to bitch at the ref since the call came from the top.
Another possible improvement would be to stop the clock whenever a sub is made. This way, makes no difference if an exiting player takes all the time in the world to hug his teammates, applaud the crowd, remove his pads, unlace his shoes, smell the roses and dance the blues.
Unless the drama is part of the shows that is
