Absolutely. And it's all about the rule book.
My favourite today was Daicos' 50 metre penalty because the North Melbourne player was too slow to give it back to him, as he was confirming who he needed to give the ball to, in order to make sure he didn't give away a 50m penalty for giving it to the wrong player.
No doubt it’s a hard game and set of rules to adjudicate.
But, the inconsistency from umpire to umpire and case to case is staggering.
Less umpires please (would potentially see a drop in inconsistency in decisions in same game), and make them full time (would potentially see a spike in performance).
Having non egomaniac umpires would also alleviate a bit of the eye test as well.
