It would be useful when looking at player page in football to know P/G and GP for each season.
For instance: https://ottoneu.fangraphs.com/football/130/player_card/nfl/5443
The game logs help a bit with this but it’d be good to know how many games a player played in each year to earn their points each season.
P/G on Roster/Lineup page might be more of a negligible help.
