When you discuss modern defense in the NFL, you won’t get very far without discussing the “Fangio system,” i.e., the series of concepts installed by legendary defensive coach Vic Fangio over the last few years. The shorthand version of “Fangio” refers to light boxes, simulated pressures, and predominantly two-high coverages with an emphasis on quarter-quarter-half (Cover-6). It’s a system that has become all the rage in the NFL today, so it was not surprising that after a year off, in which he spent time studying tape in Florida and consulting with the Philadelphia Eagles, the man himself returned to the league as the Miami Dolphins’ defensive coordinator. Fangio was the head coach of the Denver Broncos from 2019 through 2021; he was fired after a 19-30 record and no playoff appearances, but Fangio ran a defense that ranked eighth in yards allowed and third in points allowed by the time he was done.
