Indexing Issue With import_weekly_rosters

[chrismjim]

When trying to import weekly rosters I keep running into this error:

roster_data = nfl.import_weekly_rosters(years=range(2013, 2024))

+1 - also experiencing this.

Reproducible with:

years = range(2010,2024)
df_rosters = nfl.import_weekly_rosters(years)

[scrowder1172]

my work around is to get one year at a time.

weekly_rosters = nfl.import_weekly_rosters([2022])
