Referee calls, 2020: who they helped

Judgment calls helped the Chargers most in 2020: +1.90 wins, the calls that went their way minus the ones that didn’t, each weighted by the moment it came. They hurt the Chiefs most: −1.46 wins. The Cardinals were flagged the most, 112 times.

Judgment calls are the flags an official has to judge: holding, pass interference, roughing and the like. Each is valued by what it did to the helped team’s chance of winning at that moment, including any play it wiped out, so a call in a decided game counts for nothing and one at the turn of a close game for most of a win. Week to week a team’s call luck barely repeats (correlation 0.06), which is what chance looks like. How calls are valued
