Sports are, at a very basic level, about results. Every sport worth watching (and tennis) have some way of keeping score so at the end of the contest you or your team has a win, a loss, or a draw. It is easy, then, to be tempted to condense sports down to a series of equations, spreadsheets, and numbers in order to determine who the best at producing said results, which people like OPTA and Ken Pomeroy have done an incredible job of doing. This is not a hit piece railing against the rise of analytics in sports, because that is a foolish thing to rail against, but rather embracing the spectacle of sport.
