The main chart listed below ranks home stat crews according to their generosity in issuing tackles (from greatest to least). The ranking is calculated based upon the total tackles issued per tackle opportunity when compared against the league average but takes into account solo tackles being worth 2:1 to that of assisted tackles. A color key is listed next to the actual chart for your reference.
This article will be updated every Wednesday during the regular season to reflect the most up-to-date tackles issued. However, stat crews rarely change their tendencies over the course of the season and thus the trends that we witness early in the season are likely to remain for the entirety of the season.
