I, and others, often come down hard on the refs. I understand that virtually 100% of them are trying to do their best, but that doesn't mean that it is fair. It seems very clear that some games are called tighter than others. Within the game, one could argue that it is fair, but is it fair to change it from game to game?
Then there's the question of make-up calls. Was the NHL ref who got caught on a mike just trying to be fair? Are make-up calls fair? I'm sure we could argue that until next season.
Then there's the question of making the game be what their employer wishes. Frankly, I don't know if there is a wink-wink, nudge-nudge for refs to make the game close in any sport. I'm sure that refs give mercy calls to a team hopelessly behind, and sometimes that results in a closer game than expected
Being a ref is a thankless job, but unquestionably necessary.
As for machines assisting or supplanting referees, I think doing it properly is a long way off. But "properly" may not be the right bar to aim for. I work with people that have been on the forefront of image processing for more than 50 years. I remember the head of that group laughing at the thought that the technology for sideline calls in tennis that was being used was anywhere near as accurate as they portray it. The bar may just need to be set such that it treats both teams the same, even if it is imperfect. We don't yet accuse machines of treating different people differently.
(An interesting stepping stone would be fully automated touch calls in VB, but that will require a higher frame rate and more resolution than the PAC-12 uses.)
But the human referee, just like the fan that I am, may see things differently because of his beliefs and expectations. An external observer can reasonably question whether the referee was influenced by that internal state when he/she made or didn't make a call.
Indeed, one of the reasons I will question a call is when the ref is blocked from seeing the contact but still makes the call.
