Understanding NFL Passer Rating
The NFL passer rating (also called the passer efficiency rating) was created in 1973 by Don Smith, Seymour Siwoff, and Bob Carroll as part of a statistical reform effort. Before the formula existed, comparing quarterbacks across different eras and contexts was largely subjective. The formula gives a single number between 0 and 158.3 based on four passing statistics, weighted equally.
The four components are designed so that an average performance at the time of the formula's creation would score about 1.0 in each component, resulting in a rating near 66.7. At the time, a 66.7 was considered league average. Today, with improved passing games, the actual league average runs closer to 88-92, which means many quarterbacks routinely exceed what was once considered a "good" performance.
The Four Components Explained
Component A measures completion percentage. A QB who completes 77.5% of passes gets the maximum 2.375, while one completing 30% gets 0. Component B measures yards per attempt, where 12.5+ yards/attempt maxes out while 3.0 yards/attempt earns 0. Component C rewards touchdowns: an 11.875%+ TD rate maxes the component. Component D penalizes interceptions: zero interceptions earns 2.375, while a 9.5%+ interception rate earns 0.
A key quirk of the NFL passer rating is that it caps at 158.3. No matter how dominant a performance, you cannot exceed this value. This design choice makes comparisons across eras more meaningful since the formula is bounded, but it also means the metric cannot differentiate between "very good" performances that all cluster near the top.
Limitations of the Passer Rating
The classic passer rating has known weaknesses. It does not account for the difficulty of throws, receiver performance, offensive line quality, or opponent defense strength. A perfect game against a weak secondary in a garbage-time blowout scores the same as an elite performance in a championship game. The metric also treats a 10-yard completion and a 50-yard completion the same in terms of completion percentage, ignoring air yards.
For this reason, advanced metrics like ESPN's Total QBR (ranges 0-100), Pro Football Reference's ANY/A (adjusted net yards per attempt), and DVOA (defense-adjusted value over average) have become popular among analysts. These metrics attempt to contextualize performance by opponent difficulty, game situation, and other factors the classic formula ignores.
NCAA Passer Efficiency vs NFL Rating
College football uses a completely different formula developed for the NCAA. Unlike the NFL formula, the NCAA version has no maximum cap and weights the components differently. The formula rewards touchdowns heavily (330 points each) and penalizes interceptions significantly (200 points each). As a result, top-performing college quarterbacks can post efficiency ratings above 200, while a 150+ rating generally indicates a very strong season in Division I.
