Win Loss Margins (WLM) for the New Divisions

Submitted by Enjoy Life on

WLM (Win/Loss Margin) over the past 10 years. A WLM of 0 would be 6-6, +2 would be 7-5, etc.

OSU = 7.9
Wisc = 4.2
U/M = 3.8
Iowa = 3.4
PSU = 2.9
Purdue = 1.2
NW = 0.1
Minn = -0.1
MSU = -.3
Illini = -2.7
Indy = -3.9
Neb = 4.0

U/M, Neb, Iowa, MSU, Minn, NW = 10.9

The Others = 9.6

I'll update this if the divisions change.

Keep in mind that a lot of the difference is explained by PSU's really bad stretch from 2000-04, when they had four losing seasons out of five.  Now, we've also had a bad stretch, but it's only been two seasons.  If you were to restrict the data to the last five seasons, I think it would go in the other direction.

Here are the WLM for the past 5 years. (That is a relatively short time. 10 years should be more predictive of historical records.)

OSU = 7.8
Wisc = 6.0
U/M = 3.2
Iowa = 2.8
PSU = 4.8
Purdue = 0.4
NW = 0.6
Minn = -1.2
MSU = -0.2
Illini = -3.4
Indy = -3.0
Neb = 2.0

U/M, Neb, Iowa, MSU, Minn, NW = 7.2

The Others = 12.6

I agree that five years isn't normally a better indicator than ten years, but these results clearly show that a down spell for one program (PSU in the first half of the decade and UM the last two years) can have a major impact. 

All things considered, the competitive balance is reasonable.

Oops, fat fingered the formula. Those numbers are all wrong. They were for the last 5 years not including 2009. Here are the last 5 years including 2009.

OSU = 7.8  8.8
Wisc = 6.0  6.2
U/M = 3.2  1.6
Iowa = 2.8  3.0
PSU = 4.8 7.6
Purdue = 0.4  -0.4
NW = 0.6  1.2
Minn = -1.2  -1.8
MSU = -0.2  0.0
Illini = -3.4  -3.6
Indy = -3.0  -2.8
Neb = 2.0  3.4

U/M, Neb, Iowa, MSU, Minn, NW = 7.4

The Others = 15.8

Seems obvious this is not what they used to "balance". (10 year data is certainly more balanced)
