Well one of the problems could be what position they are playing at, the 2nd player could be making great oppurtunities for the first player. Also, the game engine already has the biggest miss match on the court do most of the shooting. What that means is maybe the 1st player's defender has awful OD and the 2nd player's defender has prolific OD so in theory the 1st player would make the most shots therefore more points. I hope this helps.
