My concern is people have a tendency to respond to system failure by giving more power and resources to the people running the system instead of ever acknowledging the system is broken and let's try a completely different approach. I can give examples outside of sports but it gets political and I'd rather avoid that. So let's use the NFL.
As I mentioned, it is nearly universally agreed that replay has completely screwed up the enforcement of what is a catch in the NFL. There is also widespread agreement, though not quite as universal, that the use of "incontrovertible visual evidence" (the NFL version of "clear and obvious error") means that a substantial number of replay calls, whether the field call is reversed or upheld, is essentially arbitrary and a coin flip.
Despite this, and despite no progress ever being made on either problem, the scope of replay review in the NFL has been expanded multiple times since it was first introduced, and the number of plays reviewed every game has only gone up, because -- for whatever reason -- the most powerful influencing factor in people considering replay are the instances where it works exactly as intended. There are no statistics to support or counter this, but I am reasonably certain that such plays -- the correction of an actual generally agreed-upon mistake -- constitute a rather small minority of all plays reviewed ( I would guess maybe 10-20%) , and that the coin-flip calls -- which collectively accomplish nothing except to take up time -- are almost certainly a majority (my guess 60-80% with the rest in the "correct but we never meant replay to be used for this nitpicky BS" variety). Again, I can't prove that, and might be wrong, but even if I am 100% correct and could prove it, it will never matter, because I believe people choose to endure an ever increasing number of useless and even counter-productive intrusions into game flow in order to fix a relatively small number of plays. And every failure is met with more and more use of replay. Whenever you suggest that maybe replay use should be curtailed to someone who just complained that replay is arbitrary, the response is usually along the lines of "so we should improve it, not get rid of it." Yet 30 years in there is no evidence of it ever having been improved and its usage keeps getting expanded.
In the most recent NFL playoffs the refs missed an obvious and blatant pass interference call. Pass interference has never been subject to review because everyone knows that 98% of all PI calls are subjective. But because lots of people looked at that one clear mistake and thought "something must be done" we will now have video review of PI calls, 99% of which will do nothing to improve the game. And for the next 10 years the same fools who screamed that we have to have replay for pass interference will complain that replay review of PI calls is a pointless coin flip.
