Final Results

Qualification: minimum 224 pass attempts (14 per scheduled game).

How QER is calculated

QER starts with the Pass Score, then adds a gated bonus for above-average rushing efficiency and production. The bonus is worth up to 15 points and is scaled by passing quality, so running complements passing rather than replacing it. A quarterback is never penalized for not running, and the final rating is capped at 100. 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 Efficiency

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.

Rush Production

Season-long rushing production is measured separately from efficiency:

  • Rushing yards (50% of Rush Production): Total rushing yardage.
  • Rushing first downs (30%): Total first downs gained on the ground.
  • Rushing touchdowns (20%): Total rushing touchdowns.

Rush Bonus

Only Rush Score and Rush Production percentiles above 50 receive credit. Each above-average score is rescaled from 0 to 1. The efficiency portion is worth up to eight points and the production portion up to seven points. Their combined value is multiplied by the Passing Gate (Pass Score / 100).

Rush Bonus = Passing Gate × (8 × Rush Efficiency Index + 7 × Rush Production Index)

This allows an elite passer and runner to earn as many as 15 bonus points, while a weak passer receives only a small portion of the same rushing value. Below-average or nonexistent rushing earns no bonus and never lowers QER.
