| team_ref | character | $ref URL to the team-in-season resource. |
| metric_group | character | predictive or efficiency. |
| stat_name | character | Internal metric key (e.g. fpi, offefficiency). |
| abbreviation | character | Metric abbreviation. |

| value | numeric | Metric value. |
| display_value | character | Display-formatted metric value as shown on ESPN. |

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.
