It’s become somewhat of an annual tradition for the Los Angeles Rams: celebrating the arrival of Football Outsiders’ Adjusted Games Lost (AGL) metric that quantifies the healthiest teams each season.
How does AGL work?
We have collected the data from the NFL’s weekly injury reports for every season since 2002. This allows us to measure not just who played and who didn’t, but who was able to play with injuries, even if those injuries meant the player was at something less than 100 percent. That’s why we call this metric adjusted games lost -- in addition to players who missed games entirely, we also count those who hit the field after appearing on the injury report at an adjusted rate.
