There are five categories: Points, Average Rank of Opponents, Winning Percentage of Opponents, Ranked Opponents and Bowl Eligible Opponents.
Points: These points were calculated solely on the schedule. You earn points based on certain criteria.
+0 = home game
+1 = neutral game
+2 = away game
+3 = opponent in Big Six Conference or ranked small conference opponent
+4 = ranked opponent within your own conference
+5 = ranked opponent from Big Six Conference that is not your own
-1 = FCS opponent
The points were then added together to give each team a point total per game. For example, LSU played then-ranked North Carolina at a neutral site. They earned one point for the neutral site, three points for the opponent being in the ACC and five points for the opponent being ranked from the ACC for a total of nine points for the North Carolina game.
The points were then added together for a season total.
Average Rank of Opponents: I used the ranking system that ranked all 120 teams from the FBS. If a team played the FCS, they automatically received a rank of 121. The ranks were then averaged.
Winning Percentage of Opponents: This was based solely on the win-loss record of opponents. *These totals are through November 23*
Ranked Opponents: This category gave a team a point for each Top 25 team they played. The rankings are based on when the opponent played the team.
Bowl Eligible Opponents: Each team earned a point for every bowl eligible team they played during the season. *These are bowl eligible teams as of November 23. This does not include the teams that are 5-6 and could become bowl eligible with a win.*
Whoever had the most points for each category received one point. The lowest number of points has the best overall strength of schedule.
