XFP
Expected Fantasy Points (Half PPR). The total fantasy points a player would be expected to score based on their usage and opportunities.
XFP is calculated using play-by-play data, accounting for factors like target quality, rushing opportunities, and situational context. It helps identify players who are getting good opportunities but may be unlucky (or vice versa).

OEX%
