| team_abbreviation | character | Team abbreviation; team_detail = TRUE only. |
| team_location | character | Team location / school name; team_detail = TRUE only. |
| team_display_name | character | Full team display name; team_detail = TRUE only. |
| team_short_display_name | character | Short team display name; team_detail = TRUE only. |
| team_nickname | character | Team nickname label; team_detail = TRUE only. |
| team_color | character | Primary team color; team_detail = TRUE only. |
| team_alternate_color | character | Alternate team color; team_detail = TRUE only. |

| abbreviation | character | Metric abbreviation. |
| display_name | character | Human-readable metric name. |
| short_display_name | character | Short human-readable metric name. |
| value | numeric | Metric value. |
| display_value | character | Display-formatted metric value as shown on ESPN. |

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.
