I took all the SEC games played to date and used a least squares fit to produce a strength rating for each team (using a standard 4 point home field advantage). As the scale floats, I put the weakest SEC team at zero (sorry Ole Miss).

This Week's Games

LSU by 16.48 over Arkansas
Bama by 16.90 over Auburn
MSU by 21.21 over Ole Miss
UT by 5.68 over UK


Team Ratings

LSU 43.63
Bama 37.82
Arkansas 31.15
South Carolina 27.56
Florida 27.23
Georgia 25.65
Vanderbilt 18.08
Mississippi State 17.21
Auburn 16.92
Tennessee 11.45
Kentucky 1.77
Ole Miss 0.00

I don't know what that means, but I like that we are at the top.

For example, let's say you want to predict the score of LSU at Bama. You add 4 to Bama's score and then subtract it from LSU's score. That would predict LSU to beat Bama by 1.81 points in Bama.

Error minimization. The set of numbers above produces scores to the SEC games with the lowest possible error.

And FYI, after looking at the errors it means LSU has an 84% chance of beating Arkansas.

So, if you made home field worth 3 as is common in betting, we would beat them by 2.81. Round up and you get 3... 9-6=3.

THat's what they use for the pros, but in college it seems to go 4 to 4.5 for home field.

This didn't involve burying any chicken bones in the back yard, did it?

There were no chickens involved. Only game cocks...
