Form — EAR = Elo Above Replacement, football's version of baseball's WAR (Wins Above Replacement). Every rated match scores a player against the average performance for their position: better adds to EAR, worse subtracts. EAR180 adds up the last 180 days (current form); EAR career adds up every rated match. Our predictions add EAR180 to a player's Elo, about 37 Elo points per EAR point. Each bar is the EAR180 going into that match: green above the position average, red below. A gap means no rated match in that window. (180 days)
