Theory: Initially I was looking for profitable opening game systems and wanted to test if last year's season had any relevance. I found that teams that made a bowl the previous season were a good starting point, and they fare much better at home or at neutral sites. Pure road games in the opening week are tricky so they've been omitted. I then left out any teams who were already steamed more than a point, since the value is already gone. Besides 2005, this system has been profitable every season since.
