ESPN College Football Game Power Index (Matchup FPI)

Description

Get ESPN's Football Power Index (FPI) matchup projections for both teams in a single college football game, in long format.

Usage

espn_cfb_game_powerindex(game_id = NULL, team_detail = TRUE)

Arguments

game_id	(Integer required): ESPN game identifier.
team_detail	(Logical): when TRUE (default), fetch the ESPN team catalog once and join friendly team fields next to the team_id column (see Details). Set FALSE to skip the catalog fetch and the join.

Details

Wraps the ESPN core-v2 endpoint events/{game_id}/competitions/{game_id}/powerindex. The endpoint returns one ⁠$ref⁠ per team; this wrapper dereferences each and flattens the per-team stats array into one long frame – one row per (team x FPI metric). Metrics include the predicted point differential, matchup quality, and game-projection components ESPN derives from FPI for that specific game. The long shape absorbs ESPN's habit of adding and retiring metrics across seasons.

When team_detail = TRUE (the default) the ESPN team catalog (espn_cfb_teams()) is fetched once and friendly team fields are joined in next to the team_id column – team_name, team_abbreviation, team_location, team_display_name, team_short_display_name, team_nickname, team_color, team_alternate_color, team_logo_href, and team_logo_dark_href. A catalog failure degrades to NA rather than erroring the wrapper. Set team_detail = FALSE to skip the catalog fetch and the join.
