All I'm saying is that it isn't the only way we have found to rate our teams. We use other criteria all the time. This is partly because the scoring system in football doesn't mirror the balance of a game. In tennis, it's almost impossible to outplay an opponent and lose. But in football it often happens.
Many games turn on referees' mistakes.
England won the World Cup with the aid of a goal that never crossed the line. Many of the most thrilling moments in football have nothing to do with winning or losing. Pele dummied the Uruguayan goalkeeper but missed the goal. We never tire of watching Johann Cruyff's turn against Sweden in 1974, and have forgotten that he did it during a 0-0 draw. To insist that the result is the only measure of value in football is to view the game like an accountant.
