Deciphering Football Qb Rating: What It Really Tells You About Performance

In American football, the quarterback (QB) rating is a commonly used statistic to evaluate a quarterback’s performance. While it provides a quick snapshot, understanding what it truly indicates requires a closer look at how it’s calculated and its limitations.

What Is QB Rating?

The QB rating, also known as passer rating, is a formula that combines four key passing statistics: completion percentage, yards per attempt, touchdown percentage, and interception percentage. It produces a number between 0 and 158.3, with higher scores indicating better performance.

How Is It Calculated?

The calculation involves four components:

  • Completion rate
  • Average yards per attempt
  • Touchdown percentage
  • Interception percentage

Each component is adjusted and combined into a formula that results in the final rating. This process aims to balance different aspects of passing performance into a single, easy-to-understand number.

What Does QB Rating Really Tell You?

While QB rating offers a quick overview, it has limitations. It does not account for the context of plays, such as the difficulty of throws, game situations, or the quality of the opposing defense. A high rating might come from short, high-percentage passes rather than deep, challenging throws.

Strengths of QB Rating

  • Provides a standardized measure for comparing quarterbacks
  • Easy to interpret at a glance
  • Useful for identifying consistent passers

Limitations of QB Rating

  • Ignores play context and difficulty
  • Can be skewed by a few exceptional games
  • Does not reflect overall team performance or rushing contributions

In conclusion, QB rating is a helpful tool but should not be the sole measure of a quarterback’s skill. Combining it with other stats and watching game film provides a more comprehensive understanding of performance.
