There were five undefeated teams heading into Thursday’s college football slate. One of them, the top-ranked 9-0 Ohio State Buckeyes, is the favorite to win the national championship at 6-5 odds. The other four must be getting the shaft, because 7-1 LSU is the second favorite at 9-4 odds.

Actually, the Tigers might be the best team in the nation. They’re No. 1 on the Fremeau Efficiency Index (FEI), which measures Game Efficiency as a function of a team’s winning (or losing) margins, and factors in quality of opposition.

Your other four undefeated teams are Boston College (7-1 title odds), Arizona State (6-1), Kansas (Field, 9-1) and Hawaii (75-1). Here’s where they and OSU rank in FEI:

5. Arizona State
7. Ohio State
9. Boston College
14. Kansas
50. Hawaii

If you like the FEI formula, then you should definitely like the Sun Devils at five times the championship payout of the Buckeyes.
