It's 6 categories that are not weighted, so it's not perfect. Your pass D looks great and your pts allowed a game are #7.
It was a forumla I came up with on the fly so take it with a grain of salt, this is what I did.
Passing Rank = Pass Yards a game,+,AVG Pass Yards a Game,+,TD x 100,-,INT X 100 = OFF Rating, Sorted Teams Most to LEast for Ranks 1-32.
Rush = Rush Yards a game,+,AVG Rush Yards a Game,+,TD x 100,-,FUM X 100 = DEF Rating, Sorted Teams Most to Least for Ranks 1-32.
Pass D Rank = Pass Yards Allowed, +, AVG Pass Yards Allowed, +, TD/All, X, 100 = Def Pass Ranking, Sorted teams least to most for Ranks 1-32
Rush Rank=Rush Yards Allowed, +, AVG Rush Yards Allowed, +, TD/All, X, 100 = Def Pass Ranking, Sorted teams least to most for Ranks 1-32
Pts Scored a Game = Most to LEast for Ranks 1-32
Pts allowed a game = Least to most for Ranks 1-32
AVG Rank = AVG of all categories
Team Rank = Lowest to hightest AVG Rank for teams 1-32.
So it's a bit of a Hack,but it looks somewhat accurate so far. 11 Wise is 10 though has dominated every game so far, the Defense numbers for us havn't been great so far and we have not used much of a Passing Attack. So it's accurate in terms of categoricaly ranking us, I expect it will pan out even better as the games progress.
