Unfortunately, the ability to replay plays, slo-mo, and infinite camera angles have outstripped the capabilities of 7 officials watching 22 very large, very fast and athletic human beings spread out over a large area, and intending to do violence to one another. Sure, the officials can do better … but only marginally. They’re human, and they are the best in the world at what they do. But they can’t see everything 22 cameras can, and they can’t take the time to review every call or no call in slo-mo from numerous angles. It’s just expecting too much.
But before you decide to turn NFL officiating over to automation, remember The Law of Unintended Consequences.
