Referee calls, 2020: who they helped
Judgment calls helped the Broncos most in 2020: +2.29 points a game, the calls that went their way minus the ones that didn’t. They hurt the Saints most: −3.34 a game. The Cardinals drew the most flags, 112.
Judgment calls are the flags an official has to judge: holding, pass interference, roughing and the like. Each is valued in expected points for the team it helped, including any play it wiped out. Week to week a team’s call luck barely repeats (correlation 0.06), which is what chance looks like. How calls are valued
