2020 was a strange year.
Football Outsiders has been tracking snap-weighted age (SWA) since 2006, calculating a team's age not by just averaging the ages of the players on the roster, but by weighting the age of each player by the number of snaps he played in the regular season. Most years, these articles end up covering much the same ground, as consistent trends keep rising to the top. Even 2020 wasn't quite strange enough to break every pattern.
In all but two years, the league's average age has dropped, as the benefit of players on cheap rookie contracts continues to drive roster construction.
