As expected, Ohio State drops in these rankings after a loss to Purdue, but the loss isn't as devastating as you might have expected. Each loss is worth -3 points, and while the Buckeyes only had a lead of 0.2 points on Texas in last week's rankings, the gap between it and No. 5 Florida was 4.8 points, so it only drops a spot with Michigan the new No. 5 after its win over Michigan State.
This is why Ohio State should not be considered dead in the water when it comes to the College Football Playoff. The Purdue loss certainly hurts, but Purdue could prove to be a much better team than its current record suggests. The bigger problem for Ohio State might be the TCU win looking less relevant with each passing week.

I do wonder how it would work if he updated the math for changes during the season. As I read his explanation of how it works, it just goes by if the opponent was ranked when they were played.
Very interesting that his simple system worked for almost all of the previous seasons.
