I see your point, but the difference with the NFL is that each team plays defense against the other team and has an impact on how many points their opponent scores. With FFL, that is not the case and there is a little more luck involved - i.e. their top players may have been on bye, injured, or had tough matchups. So while you may have beat them in the two weeks you played each other, the other 12 weeks they may have outscored you.
