    That is exactly why Arizona is where they are and Buffalo is where they are.

    My current rank calculation is SQRT(Winner's Rank)/Loser's Rank + 1. This gives it an exponential quality to the modifier. I'm open to suggestions on better ways to quantify it as this was the formula that had no statistical reasoning behind it, just sort of felt right, if ya dig?

    In my opinion the team you play is probably the most important part of the calculation but maybe it is too highly weighted. For example, Arizona's win was worth 2.04 points for winning by 24 and 3.35 points for beating the #2 ranked team as the number 22 team (these are multiplied by 1.72 for winning at home)

    If you're not attempting to predict, then injuries are a non-factor.

    That doesn't make much sense to me as the Jets beat two teams ranked ranked way above them that both have the same record (2-2).

    edit: oops - the cards are 3-2 now.

    Our one win against the Dolphins was essentially negligible because it was week 1 and no teams were ranked and it was by a slim margin. Our "Credit" came from winning on the road.

    The idea would be along the lines of was Buffalo that bad in their last loss to Arizona or was JP Losman that bad that he lost it for Buffalo? In other words should a bad loss with a big injury factored in count as much as a bad loss with a fully healthy team. Obviously not but how to factor that in is the difficulty.

    Notes:
    ? Ranks are calculated based on Points Margin, Home/Away and Strength of Opponent for each game and summed over the season.
    ? Ranks are based on an absolute sum not averaged over games played (teams with less games played will be at a disadvantage).
    ? The rank differential portion of the calculation is based on the prior weeks ranks. Early season game rank multipliers might be significantly different from their late season counterparts
    ? Win Loss, Home/Away, PPG and Stength of Schedule are shown as reference only and are not explicitly used in the calculations.

    Another week another outlier…

    Cleveland is obviously not the number 1 team in the league and it is now a certainty that I have to tweak the rank modifier. Arizona managed to back up their status much the same as Miami did when they jumped up and its possible Cleveland does the same and we all point to this victory as the moment their season changed. However, that is unlikely. Just by beating the then #1 team doesn’t mean you get to take their place. Similarly, because you had one loss to a bad team doesn’t mean you are one of the ten worst teams in the league. Was Cleveland’s victory 60% as impressive as Arizona’s shellacking of Buffalo? Maybe but that doesn’t mean Arizona’s victory was properly weighted.

    Again, I am open to suggestions on how to determine how important a victory is based on the rank of the two teams playing or citations of how other rankings have dealt with it. As of now, I expect to tweak it and restate my rankings beginning this week.

    Why didn't STL beating WAS bump them up?

    6 slots in ranking and point differential help.

    Rambo I have a feeling as the season gets closer to a close your formula will be pretty much dead on. But in the early portions of the season, it is off simply because there isnt enough data to run with. As you obtain more data say 10 games per team, my bet is your rankings become nearly dead on.

    Well that was always kinda the plan in the back of my head. Volatile up front and better on the back end once both the teams stabilize (losing teams tend maintain that losing mentality and vice versa). However, I think it is still too off but maybe I'm wrong. I'm going to tinker a little this week and maybe even come up with multiple strategies for dealing with things going forward.

    I appreciate the enthusiasm and confidence. It is nice to hear.

    I essentially cut the points gained based on the rank of your opponent in half and I think it is a much better representation.

    1. Tennessee is the clear cut #1 team until they lose.
    2. Chicago is very strong. Their losses have been by 3, 3, and 2 points.
    3. TB, as much as I hate to admit, is equally strong having lost by 4 and 3 points and playing only top 20 teams. They beat Chi but are hurt because they have 3 of 4 wins at home.
    4. Arizona, another surging team with 2 big weeks. The Dallas game actually wasn't that impressive in my calculations as they won by a small margin at home. The Buffalo shellacking accounts for much of their ranking
    5. Dallas is sliding with only 1 decent win over GB and a couple close losses.
    6. San Diego, boosted by their last win they have been hurt by the level of competition they played haven't been dinged too much on their losses.
    7. Philadelphia, when they win they tend to win big and when they lose they tend to lose by very little against good opponents.
    8. New Orleans, their points have come almost exclusively from their last win over Oakland and show the most potential to drop. On the other hand they have some injuries that may determine their success one way or the other.
    9. New York Giants, would be number 1 had they not got embarrassed on Monday Night Football
    10. Cleveland, gained two slots from not playing week 5(!) and 16 from beating the Giants. Two game win streak has been solid and they look to be returning to form. If they keep it up they will justify a top ten ranking and if they don't it is back to the cellar.

    Pittsburgh is the most underwhelming #2 team...

    If you did a simple list based on point differential, I think the rankings would be more intuitive. Note how NYG and Buffalo get bumped up while Chicago and Arizona get knocked down. I think most fans would agree with that. And NE gets a big raise (which they deserve after last night) and Cleveland gets dumped. All of that makes sense.

    I disagree. You have to be cognizant as to where those points were scored and how. For example, New England has had one good game pointswise (and that was against a team missing their starting QB and RB). Their weekly differentials have been 7, 9, -25, 9, -20, 34. The average team wins by 12.4 points each game. I would consider last nights win an aberration at this point, an outlier that I am seeking to average out rather than let it significantly influence the rankings.

    On the other hand, the Giants have won two games by 28 and 38 points which are the reasons their point differential is so high. Who did they beat by those wide margins? #29 St. Louis and #28 Seattle. Tampa Bay has won by more than average against the #7 and #17 teams and has only lost by a combined 7 points (NYG lost by 3 times as much in their 1 loss!).
