In a nutshell, the ranking system is calculated by taking a team's offensive scoring output for each game and subtracting from that the average score given up by the opposing team... Then taking the score given up by the team and subtracting from that the average scoring output of the opponent. So a team gets an adjusted offensive and defensive score for each week. I take the average of the offensive scores and subtract from that the average of the defensive scores, to get my final value.
Note: I subtract 7 points from each team's game score for defensive touchdowns. My reasoning behind this is that the offense won't get credit for their D scoring, and the opposing O loses points for giving up 7.
