1. What is Adjusted Yards Per Attempt?

Adjusted Yards Per Attempt (AYA) is a quarterback efficiency metric that accounts for passing yards, touchdowns, and interceptions relative to pass attempts. It provides a more comprehensive measure of quarterback performance than simple yards per attempt.

2. How Does the Calculator Work?

The calculator uses the AYA formula:

Where:

• \( PY \) — Passing yards
• \( TD \) — Touchdown passes
• \( INT \) — Interceptions thrown
• \( A \) — Pass attempts

Explanation: The formula rewards touchdowns (20 yards equivalent) and penalizes interceptions (45 yards equivalent) to provide a more accurate measure of quarterback efficiency.

3. Importance of AYA Calculation

Details: AYA is a valuable metric for evaluating quarterback performance, comparing passers across different eras, and analyzing offensive efficiency in football analytics.

4. Using the Calculator

Tips: Enter passing yards, touchdowns, interceptions, and pass attempts. All values must be valid (attempts > 0, non-negative values for other inputs).

5. Frequently Asked Questions (FAQ)

Q1: Why use 20 and 45 as coefficients?
A: These values were derived from statistical analysis showing touchdowns are worth approximately 20 yards and interceptions cost about 45 yards in terms of field position impact.

Q2: What is a good AYA value?
A: Generally, AYA values above 7.0 are considered excellent, 6.0-7.0 is good, 5.0-6.0 is average, and below 5.0 is below average.

Q3: How does AYA compare to passer rating?
A: AYA is often considered a simpler and more transparent metric than traditional passer rating, while still providing meaningful quarterback evaluation.

Q4: Can AYA be used for college football?
A: Yes, AYA can be applied to college football statistics, though the coefficients were originally developed for NFL analysis.

Q5: Are there limitations to AYA?
A: Like all metrics, AYA doesn't account for factors like receiver performance, offensive line quality, or game situation context.
