ESPN College Football Power Index (Long Format)

Description

Get ESPN's College Football Power Index (FPI) ratings for a season, including the full set of predictive metrics and efficiency components ESPN publishes alongside the headline FPI number.

Usage

espn_cfb_powerindex(year = NULL)

Arguments

year	(Integer required): Season, 4 digit format (YYYY). Minimum value accepted: 2005

Details

Wraps the ESPN core-v2 endpoint sports.core.api.espn.com/v2/sports/football/leagues/college-football/seasons/{year}/powerindex. Returns one row per team-metric in long format: each team contributes one row for every predictive metric (FPI, projected wins, strength of record, ...) and every efficiency component (offensive, defensive, and special-teams efficiency, ...). The long shape is deliberate – ESPN adds and retires metrics across seasons, and a long frame absorbs that drift without breaking column expectations. Pivot wider with tidyr::pivot_wider() keyed on stat_name when a wide table is wanted.
