2017 NCAA OFFENSIVE LINE STATS

Updates begin after Week 7 of the college football season

Pulling the ideas mostly from Football Outsiders’ pro stats, below are the following offensive line stats for each of FBS' 128 schools.

Run-blocking stats

  • Adjusted Line Yards: One of only two opponent-adjusted numbers on the page, this aligns with the ALY figure FO tracks for the NFL and is presented on a scale in which 100.0 is perfectly average, above 100 is good, below 100 is bad.
  • Standard Downs Line Yards per Carry: The raw, unadjusted per-carry line yardage for a team on standard downs (first down, second-and-7 or fewer, third-and-4 or fewer, fourth-and-4 or fewer).
  • Passing Downs Line Yards per Carry: The same unadjusted averages for rushing on passing downs.
  • Opportunity Rate: The percentage of carries (when five yards are available) that gain at least five yards, i.e. the percentage of carries in which the line does its job, so to speak.
  • Power Success Rate: This is the same as on the pro side -- percentage of runs on third or fourth down, two yards or less to go, that achieved a first down or touchdown.
  • Stuff Rate: Same as STUFFED on the pro side -- percentage of carries by running backs that are stopped at or before the line of scrimmage.

Pass-blocking stats

  • Adjusted Sack Rate: An opponent-adjusted version of a team's sack rate -- sacks divided by (sacks plus passes), presented on a scale in which 100 is perfectly average, above 100 is good, below 100 is bad.
  • Standard Downs Sack Rate: Unadjusted sack rate for standard downs pass attempts.
  • Passing Downs Sack Rate: Unadjusted sack rate for passing downs pass attempts.
