Many pundits think that even football has found austerity. They blame the dearth of transfers on the financial crisis, or on new rules intended to stop clubs losing money. However, austerity isn’t the whole story. Something more fundamental is happening: transfers are going out of fashion.
This paper aims to resolve a question of superficial triviality: when sports use instant replay technology to review on-field calls, what standard of review should they employ? The conventional view is that on-field calls should be entrenched against reversal such that, if the reviewing official has any doubt about the correctness of the initial call, he should be instructed to let it stand - even if he thinks it very probably wrong. Indeed, in the wake of officiating debacles at last summer’s FIFA World Cup, many observers proposed not only that soccer introduce instant replay, but also that its governing bodies adopt the NFL rule directing that on-field calls be overturned only when the referee sees “indisputable visual evidence” (IVE) that that call was mistaken. In a small nutshell, this essay argues that conventional wisdom in favor of IVE likely rests upon mistaken premises, and offers several concrete proposals for reform.
Let’s start with the premise that an indispensible requirement of sprint competition is that all racers must start simultaneously. That is, a sprint is not a time trial but a head-to-head competition in which each competitor can assess his standing at any instant by comparing his and his competitors’ distance to a fixed finished line. Then there must be penalty for a false start. The question is how to design that penalty.
The pace and flow of soccer generally make it difficult for managers to affect the outcome of a match once it begins. Since soccer has almost no stoppages for coaches to draw on clipboards or strategize with their players, a manager’s most critical in-game decision may be choosing when to utilize his three substitutions. That’s where Bret Myers, a professor of management and operations at the Villanova School of Business, comes in. A lifelong soccer player and fan, he sought to help coaches make their subs at exactly the right moment and discovered what he calls the “Decision Rule.”
