Downloads and parses regular season ESPN QBR data from ESPN's API.
To use, just cd into the root directory of the repo and run python qbr_scrape.py.
composite_qbr.csv is updated weekly via GitHub action with the latest data from ESPN.
qbr.R has sample code to generate a GAM for QBR based on QB EPA (h/t @guga31bb).
qbr_xgb.R has some code to generate an XGBoost powered model to estimate ESPN's opponent-adjusted QBR. xqbr_xgb.csv has results for week-by-week expected QBR based on this model.
