nflreadr is a minimal package for downloading data from nflverse repositories. It includes caching, optional progress updates, and data dictionaries.
Please note that nflverse data repositories have been reorganized and pushed towards the nflverse-data repo, and v1.2.0+ is the minimum version that supports this change. We encourage all users to upgrade to this version immediately.
For Python access to nflverse data, please check out nfl-data-py - maintained by Cooper Adams.
