Putting a clock on video review changed what officials find

Time limits imposed to protect the flow of a match also decide how deep an examination of an incident is allowed to go.

Reviews were getting long. Crowds stood around, momentum drained out of matches, and broadcasters filled the silence with a graphic and a shrug. So the sports that use video review started imposing limits. Sixty seconds, ninety, a soft target enforced by a supervisor in an earpiece.

That is a reasonable response to a real problem. It also changed the nature of the decision without anybody voting on it.

A time-limited review is a search under constraint. The official gets the angles that load first, at the frame rate the system offers, in the order the operator queues them. What they do not get is the fourth look at the one camera that would have settled it, because the clock is running and there is a strong institutional preference for not being the person who held up a match for three minutes. The standard of proof has not changed on paper. In practice, a limit converts clear and obvious into clear and obvious within ninety seconds.

Those are different tests, and the difference falls on complicated incidents rather than simple ones.

I would argue the sports have this backwards. The reviews that take a long time are precisely the ones where the on-field call is most likely to be wrong, because a straightforward error resolves in fifteen seconds. Capping the process therefore protects flow at the direct expense of the decisions with the greatest chance of being unjust.

There is an inconsistency problem sitting alongside. Some competitions stop the clock during a review and some do not. Where the clock keeps running, added time is supposed to compensate, which pushes the compensation decision onto the fourth official, who is estimating. So a review that takes two minutes might cost a losing team two minutes of playing time or might cost it nothing, depending on which country the fixture is in.

Teams have noticed. Requesting a review, where requests are permitted, has become a way of managing tempo as much as a way of correcting an error, and the officials know they are being used.

If the sport is going to time reviews, publish the clock. Put it on the screen, let everyone see it run.

An unseen limit is not a rule. It is pressure.
