A Proposal for Replay in 30 Seconds or Less
You probably already know why I’m writing this post (but if you’re reading this in 2014, Armondo Gallaraga was robbed of a perfect game in the 9th with 2 outs on 6/2/2010.)
Replay gets discussed a lot these days, and there are those in favor of it and those against it. The main reason for it is that replay is more accurate than an umpire, which has been demonstrated over and over again. There are two reasons against it. One is the tradition of umpires, the other is that it will slow down the game. As far as I can tell, it’s futile to argue with people when they love the tradition enough: if you’re sufficiently committed to tradition, no other value will persuade you to give up your stance. I don’t share that love of tradition, but I won’t enter a futile argument here either.
The lost time due to replay is different. We can count seconds and we can try to balance lost time with increased accuracy. Moreover, as technology improves the amount of time lost rewinding tapes and whatever else they had to do in the NFL in the 1980s goes away. So, theoretically, 100% of time used for review is actually spent making a decision. How much time is worthwhile? We’d have to have a discussion about that, but I’m going to throw out 30 seconds. If we could have 30 second replay, it would be worth it. A controversial call on the field typically takes more than thirty seconds anyway, because umpires huddle (but never change the ruling) and managers come out on the field and argue the call (which never has any effect except to get the manager removed from the game.)
Still, it takes a long to time review the play from every angle to come up with the best judgment that the video evidence supports. You just couldn’t do all the work necessary in 30 seconds, so it looks like we’ll have to settle for a longer review time or sacrifice the accuracy we desire.
That is a mistake. The reason replay takes so long is that we think that the goal is to produce the best judgement that the video evidence supports, using time the way we should in a courtroom, where no minute is more valuable than the freedom of the innocent-but-accused. The reviewer must check the play from all angles. He must double check it. He must confer with other reviewers for their opinion, and then come to a consensus. It’s an inefficient system, which in criminal trials is fair and good, but it’s not good for entertainment.
Replay doesn’t have to be a courtroom. Give five reviewers access to all the available video. Give each 30 seconds to decide what the call should have been. Then the vote. They don’t talk about it, they just vote their own best judgment. No changing the vote once cast. The majority rules the day. Suppose for a moment that there is a .75 probability that each of them makes the right call. Then the probability that the majority is correct is .896. (Binomial distribution probability.) Such reviewers would botch the call (as a group) just 1 in 10 times. Furthermore, in the preponderance of replay cases, video evidence is completely clear cut and it takes less than 30 to make a determination that’s right with a probability of 1.
This 30 second replay system would eliminate the vast majority of all erroneous calls in baseball. It wouldn’t be a fail safe system. It would require that we abandon our standard of having evidence that fully justifies our conclusions to all so that no one could come to a better conclusion on the basis of the evidence. But we shouldn’t let perfection be the enemy of the good. And it’s a good thing to preserve perfection.
