Like usual, I'll preface my suggestion by saying I'm relatively new, so if there is a way to do this and I just don't know it, I'm happy to be pointed in the right direction.
I can only find play count stats for the whole season, not game by game. When making tough depth chart decisions, especially around the 44-46 man mark, it would be good to know in recent games who has been on the field compared to who you think has been on the field.
For example, I think I need a lot more O-line depth to my depth chart than in reality, even seeing players pop up in the play by play as injured, but I can't be sure of it right now. If a back up lineman has 40 plays on the season, did they all come in one game after a guy went down? Or is he averaging 5 snaps a game?
