The Fremeau Efficiency Index (FEI) considers each of the nearly 20,000 possessions every season in major college football. All drives are filtered to eliminate first-half clock-kills and end-of-game garbage drives and scores. A scoring rate analysis of the remaining possessions then determines the baseline possession efficiency expectations against which each team is measured. A team is rewarded for playing well against good teams, win or lose, and is punished more severely for playing poorly against bad teams than it is rewarded for playing well against bad teams.

  • OFEI: Offensive FEI, the opponent-adjusted efficiency of the given team's offense.
  • OE: Offensive Efficiency, the raw unadjusted efficiency of the given team's offense, a measure of its actual drive success against expected drive success based on field position.
  • FD: First Down rate, the percentage of offensive drives that result in at least one first down or touchdown.
  • AY: Available Yards, yards earned by the offense divided by the total number of yards available based on starting field position.
  • Ex: Explosive Drives, the percentage of each offense's drives that average at least 10 yards per play.
  • Me: Methodical Drives, the percentage of each offense's drives that run 10 or more plays.
  • Va: Value Drives, the percentage of each offense's drives beginning on its own side of the field that reach at least the opponent's 30-yard line.
  • OSOS: Offensive Strength of Schedule, the likelihood that an elite offense (two standard deviations better than average) would have an above-average OE rating against each of the defenses faced by the given team.

Overall ratings and splits for Offense, Defense, Special Teams, and Field Position can be found using the drop-down menus provided above. Other supplemental drive-based data can be found here.

FEI Offense will be updated beginning after Week 7 of the college football season.
