The season_play_by_play folder contains play-by-play datasets for each regular season game in each season from 2009-2016. The files are separated by season. Each dataset contains 100 columns (see the nflscrapR game_play_by_play() and season_play_by_play() function documentation for descriptions).
Through list manipulation using the do.call and rbind functions a 13 column dataframe with basic information populates directly from the NFL JSON API. These columns include the following:
"Drive" - Drive number
"sp" - Whether the play resulted in a score (any kind of score)

"desc" - A detailed description of what occured during the play
Through string manipulation and parsing of the description column using base R and stringR, columns were added to the original dataframe allowing the user to have a detailed breakdown of the events of each play.

The season_player_stats folder contains datasets with player statistics at the season level, while the game_player_stats contains datasets with player statistics at the game level. There are 3 types of datasets in each folder:
- Passing
- Receiving
- Rushing
Both game and season level have a Team column with the abbreviation for which team the player was on. The game level datasets contain a column for the opponent's team.
The season_team_stats and game_team_stats folders contain the same statistics but at the team level, with the first player list being the most prevalent player.
The datasets contain traditional stats as well as expected points added (EPA) based metrics. See here for which stats are more predictable on a seasonal basis (HINT: not all yards are created equal)
