I find myself explaining Goodhart's Law a lot. Wittering on about Russian nail factories. Which is probably unhelpful.
Fortunately, now, there's this bit from Expected Goals, Rory Smith's book about football data.
"Manchester City’s squad noticed that Pablo Zabaleta, their dogged and industrious right-back, had a habit of sprinting across the field during lulls in play. He had worked out that doing so helped him improve two key physical metrics: total distance covered and the number of high-intensity sprints he had produced. Others shuttled across the field while their own team was taking a corner. Tal Ben Haim, an Israeli central defender who played for both Bolton and Chelsea, won a reputation for playing endless short passes to his defensive partner to ensure his pass completion percentage was as high as it could be."
