The Net Run Rate (NRR) system has been employed as a general practice in the ranking and scoring of teams in competitive tournaments within the keenly followed and lucrative sport of Cricket. Despite its imposition by the International Cricket Council (ICC), the NRR method has come into ever greater scrutiny because of its severe impact on the rankings of teams at critical junctures. This working paper aims to delineate the calculation of this method and then highlight the glaring limitations of this approach, including: miscorrelation, outlier bias, wicket-factoring, manipulation & distortionary incentives, complexity bias, close-calls, unplayed matches, and incomplete matches. The findings of the working paper suggest that a replacement of this method will increase the perception of fairness in Cricket and also reduce the risks of metric manipulation.
