What is WOPR?
“WOPR stands for Weighted Opportunity Rating. It takes a player’s target share and share of team Air Yards and combines them in a way that best predicts both PPR and standard fantasy points. The formula for WOPR is:
1.5 * Target Share + 0.7 * Share of Team Air Yards
This opportunity rating combined with a player’s PPR points can help us spot players who under-produced their volume. In other words, WOPR helps us spot buy-lows both in-season and between seasons.”
