From: | To: |
The NFL/NCAA QB Passer Rating (officially known as the "Passer Rating") is a measure of a quarterback's passing performance. Despite its name, it's not an official NFL formula but is commonly used in both NFL and NCAA football to evaluate quarterbacks.
The calculator uses the QB Passer Rating formula:
Where:
Explanation: The formula accounts for four key aspects of passing: completion percentage, yards per attempt, touchdowns per attempt, and interceptions per attempt.
Details: The passer rating is a standardized measure that allows comparison of quarterbacks across different games, seasons, and eras. It's widely used by analysts, coaches, and fans to evaluate quarterback performance.
Tips: Enter all passing statistics from a game or season. All values must be non-negative integers. Pass attempts must be greater than zero for calculation.
Q1: What is a good QB rating?
A: In the NFL, a rating of 90+ is generally good, 100+ is excellent, and 158.3 is perfect. NCAA ratings tend to be higher due to different defensive schemes.
Q2: How does this differ from the NFL official formula?
A: This is actually the NCAA formula. The NFL formula is more complex with different coefficients and caps on each component.
Q3: What are the limitations of this rating?
A: It doesn't account for sacks, rushing yards, fumbles, or game situations. It also overweights completion percentage.
Q4: Can the rating be negative?
A: Yes, theoretically, though in practice it's very rare. A negative rating indicates extremely poor performance.
Q5: Why is this called "passer rating" not "QB rating"?
A: Because it only measures passing performance, not overall quarterback play which includes rushing, decision-making, etc.
