Details
Wraps the ESPN core-v2 season athlete index
sports.core.api.espn.com/v2/sports/football/leagues/college-football/seasons/{year}/teams/{team_id}/athletes.
The index returns one $ref per athlete; this wrapper dereferences each
athlete resource and flattens it into a row. The site-v2 roster endpoint
is deliberately not used: it returns only the team's current
roster and silently ignores a season query parameter, so it cannot
deliver historical rosters. The core-v2 path used here is genuinely
season-scoped.
Because each athlete is dereferenced individually, a full roster is roughly 150-220 HTTP requests; allow a few seconds per call.
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, inserted immediately after
team_id. A catalog failure degrades to NA rather than erroring the
wrapper. Set team_detail = FALSE to skip the catalog fetch and the
join.
When position_detail = TRUE (the default) the ESPN position catalog
(espn_cfb_positions()) is fetched once and joined onto the
position_id column, appending the five position_* detail columns
(position_name, position_display_name, position_abbreviation,
position_leaf, position_parent_id). A catalog failure degrades to
NA rather than erroring the wrapper. Set position_detail = FALSE to
skip the extra fetch and the join.
