NFL — additional Python functions — Play-by-play processing: shield_nfl–team_name

shield_nfl_pbp​

shield_nfl_pbp(game_detail: 'Optional[Dict[str, Any]]' = None, shield_game_id: 'Optional[str]' = None, *, enrich: 'bool' = True, context: 'Optional[Dict[str, Any]]' = None, game_id: 'Optional[str]' = None) -> 'pl.DataFrame'

Build one NFL game's nflverse-shape play-by-play from Shield, at ANY game phase.

The live entry point: the same parser build_pbp runs on the archived nfl/raw finals, plus the four things a game still being played needs — the in-progress drive's possession, game-outcome columns held null until the feed says FINAL, a next-snap row from summary, and provisional rows flagged (see sportsdataverse.nfl.shield_pbp.live). Safe to poll: pass the payload you already have via game_detail (no network), or a shield_game_id to fetch it.

Parameters

ParameterTypeDefaultDescription
game_detailOptional[Dict[str, Any]]NoneA Shield experience/v2/gamedetails payload (the raw body, or a {"data": ...} envelope). Takes precedence over shield_game_id, so tests and pollers that already hold a payload never touch the network.
shield_game_idOptional[str]NoneShield game uuid, fetched via sportsdataverse.nfl.nfl_game_details_v2 with include_drive_chart=True, return_parsed=False when game_detail is None.
enrichboolTrueRun sportsdataverse.nfl.ep_wp.enrich_nfl_pbp on the result (default True) for the nfl_model_pbp EP/EPA/WP/WPA/CP/CPOE columns. Pass False for the base frame only (no model loads).
contextOptional[Dict[str, Any]]NoneGame context {"roof": ..., "spread_line": ..., "total_line": ...} the Shield feed omits. Unset fields fall back to the nflverse schedule row for this game, then to live.DEFAULT_CONTEXT (outdoors / 2.5 / 55.5, the same default the ESPN processor uses).
game_idOptional[str]NoneOverride the nflverse game_id (computed from the payload when None).

Returns

A polars DataFrame, one row per play (plus, while summary.phase is INGAME, one current-situation row), carrying the nfl_model_pbp columns — the build_pbp base frame, the EP/WP enrichment when enrich is True, and: | col_name | type | description | |----------|------|-------------| | live_phase | str | The payload's summary.phase: PREGAME, INGAME, HALFTIME, FINAL or FINAL_OVERTIME. | | is_play | int | 1 for a real play; 0 for the feed's GAME_START / END_QUARTER / END_GAME markers and the current-situation row. | | provisional | int | 1 when the feed has not closed the play (playEndTime null) and it is in the trailing run of such plays of a non-final game — its text, yardage and stats may still change. Always 0 on a final game. | home_score / away_score / result are null until the game is final. The current-situation row is not inert once enrich is True: it is the next state, so it also completes the previous play's lead-diff columns (epa, qb_epa, wpa, vegas_wpa, the total_* running sums). That play is usually still provisional, so those values can move on the next poll. A payload Shield has not populated a drive chart for (every scheduled game before kickoff) returns a zero-row frame carrying only the three live columns — check df.is_empty() before selecting anything else.

ParameterTypeDefaultDescription
game_detailMapping[str, Any]A Shield experience/v2/gamedetails payload (raw body or a {"data": ...} envelope) -- the same object sportsdataverse.nfl.shield_pbp.build.shield_nfl_pbp consumes.
idmap_rowMapping[str, Any]The game's pre-kickoff id-map row (sportsdataverse.football.sources.idmap.GAME_SCHEMA): espn_event_id, home_espn_team_id and away_espn_team_id are required; the optional home_team / away_team sub-dicts supply the era-correct espn_abbr.
parsedOptional[DataFrame]NoneThe frame shield_nfl_pbp(game_detail, enrich=False) already produced. Built here when None -- pass it to parse the payload once for both projections.
oddsOptional[Mapping[str, Any]]None{gameSpread, overUnder, homeFavorite, gameSpreadAvailable} (the stored closing line, sportsdataverse.football.sources.idmap._odds_override_from_row). Becomes the summary's one-provider pickcenter.
player_statsOptional[Mapping[str, Any]]NoneA Shield /football/v2/stats/live/player-statistics/{gameId} body. Becomes boxscore.players in ESPN's exact shape (ten categories, athletes carrying ESPN ids from the players crosswalk). Omitted -> the box stays empty and no ESPN athlete id is attached to any play.
team_statsOptional[Mapping[str, Any]]NoneA Shield /football/v2/stats/live/team-statistics/{gameId} body. Becomes boxscore.teams -- the authoritative countable team totals NFLPlayProcess.create_box_score prefers over its play-by-play derivation.

Returns

(summary, notes). | item | type | description | |---|---|---| | summary | dict | An ESPN-summary-shaped payload: header (season/week/competitions/competitors/status), drives.previous (+ drives.current while the game is live), gameInfo, pickcenter, boxscore (filled when player_stats/team_stats are given) and passthrough arrays. Feed it to espn_nfl_pbp(summary=). | | notes | list[str] | Adapter-side degradations worth surfacing in provenance: a missing summary.timeouts block, a missing summary.homeTeam/awayTeam team id, a PAT with no touchdown to fold into, plays outside the drive chart, and (pre-2014) play ids that do not join ESPN's own. |

Example

import json
from sportsdataverse.nfl import NFLPlayProcess, shield_to_espn_summary

# any Shield gamedetails body -- here the copy nfl-raw keeps
with open("nfl/raw/2025/2025_07_LA_JAX.json") as fh:
game = json.load(fh)
row = {"espn_event_id": "401772635", "home_espn_team_id": "30", "away_espn_team_id": "14"}
summary, notes = shield_to_espn_summary(game, row)
proc = NFLPlayProcess(gameId=401772635, join_participants=False)
proc.espn_nfl_pbp(summary=summary)
result = proc.run_processing_pipeline()

team_name_fn​

team_name_fn(expr: 'pl.Expr') -> 'pl.Expr'

Fold historical/relocated team codes onto their current abbreviation.

Verbatim port of nflfastR's team_name_fn (a plain stringr::str_replace_all over a 10-entry named vector). Operates as a substring replace (not a full-value lookup) so it also fixes embedded codes like "SD 49" -> "LAC 49" on yard-line columns. The 10 from-codes are disjoint from all of their to-values, so the order of the 10 sequential replacements does not matter (verified in tests.nfl.test_nfl_clean).

Parameters

ParameterTypeDefaultDescription
exprExprA polars.Expr over a Utf8 column (e.g. pl.col("posteam")).

Returns

The same expression with every occurrence of the 10 historical codes replaced by their current-franchise code.
