More season analysis

This is the number of wins predicted for the season, by week compared to the actual final record of each team.

1---2.656---7---11---16
2---2.469---3---12---18
3---2.250---9---13---18
4---2.188---5---11---19

16--0.563---18--28---32
17--0.313---22--32---32

Using all my data, I made a formula, which I think shows a teams improvement or decline over the season.

A positive number indicates improvement while a negative number indicates getting worse.  0 would be almost no change at all from the start of this year.  Keep in mind if a good team is negative, that it is in comparison to itself, not an average team.  Same goes with a bad team being positive.  Anything between -1 and +1 is pretty minimal.  This is really to show the extremes.  Now you can really see how much of an underachiever the Jets were this year.

So, without further ado... teams from biggest decline to most improved:

32. Jets: -3.176
31. Buccaneers: -2.118
30. Chargers: -1.765
29. Redskins: -1.471
