Final Results

Qualification: minimum 210 pass attempts (14 per scheduled game).

How QER is calculated

QER starts with the Pass Score, adds a bonus worth up to five points for rushing, and is capped at 100. A quarterback is never penalized for not running. All percentiles are calculated among qualified quarterbacks from the same season.

QER = min(100, Pass Score + Rush Bonus)

Pass Score

The Pass Score combines Passing Efficiency (75%) with Production (25%).

Passing Efficiency

  • Success percentage (30% of Passing Efficiency): How often pass plays meet the success criteria for the down and distance.
  • Yards per attempt (25%): Passing yards gained per attempt, rewarding efficient downfield production.
  • Interception avoidance (20%): Rewards a lower percentage of attempts resulting in interceptions.
  • Passing first-down percentage (15%): The percentage of attempts that produce a first down.
  • Completion percentage (10%): The percentage of pass attempts completed.

Production

  • Passing yards (50% of Production): Total passing yardage over the season.
  • Passing touchdowns (30%): Total touchdown passes.
  • Passing first downs (20%): Total first downs produced through the air.

Rush Score

Rushing production is measured per quarterback play, where QB plays = pass attempts + sacks + rushing attempts. This prevents a small number of carries from dominating the rating.

  • Successful rushes per QB play (30% of Rush Score): Estimated successful carries based on rushing attempts and rushing success percentage.
  • Rushing first downs per QB play (25%): How often rushing creates a first down.
  • Rushing yards per QB play (25%): Rushing production relative to the quarterback’s total workload.
  • Rushing touchdowns per QB play (10%): Rushing scoring production relative to total workload.
  • Fumble avoidance per QB play (10%): Rewards quarterbacks who protect the football across their total workload.

The Rush Score is multiplied by 5% to create the Rush Bonus. A perfect Rush Score adds five points; a quarterback with no rushing value loses no points.
