Description

Is there an existing issue for this?
  • I have searched the existing issues
Have you installed the latest development version of the package(s) in question?
  • I have installed the latest development version of the package.
If this is a data issue, have you tried clearing your nflverse cache?

I am not using an nflverse R package (nflreadr, nflfastR) to access this data.

What version of the package do you have?

nflreadpy 0.1.5 (latest release on PyPI). Using the Python client, not the R packages.

Describe the bug

Exactly one row in load_player_stats(summary_level="week") has team and
opponent_team set to NULL: Steve Bono, 1999 week 9.

This appears to be the only occurrence in the dataset. I checked all 476,159
weekly rows across every position and every season from 1999 onward, and it is
the sole row with a null team.

game_id is populated: 1999_09_PHI_CAR. Bono was
on Carolina in 1999, making team = CAR and opponent_team = PHI.

I hit this because my ingest pipeline has a foreign key to a teams table, so the
row fails to load.

Reprex
import nflreadpy as nfl
import polars as pl

nfl.clear_cache()

w = nfl.load_player_stats(seasons=True, summary_level="week")

print(w.height)
# 476159

print(
    w.filter(pl.col("team").is_null())
     .select("player_id", "player_display_name", "position",
             "season", "week", "game_id", "attempts")
)
# [{'player_id': '00-0001471', 'player_display_name': 'Steve Bono',
#   'position': 'QB', 'season': 1999, 'week': 9,
#   'game_id': '1999_09_PHI_CAR', 'attempts': 1}]
Expected Behavior

team should be CAR and opponent_team should be PHI.

Research direction

Start at the load_player_stats(summary_level="week") entry point and trace the source data for game_id 1999_09_PHI_CAR, player Steve Bono, in week 9 of 1999. Verify the row's team and opponent_team values, then rerun the provided Polars check to confirm they are CAR and PHI and that no affected null remains.
