Now:
Score = SUM(own goals / other team goals) / number of games played
Wanted:
Score = some kind of magic done based on the other players score. An example could be
Score = Oldscore / (Teammates score) * (Opponents score) which would raise your score if you play with players < 1 score (average) and lower your score if you play with great players. Reason for this would be that it's probably your great teammates who's resulted in your team winning and so on.
