Adjusted Passing Yards per Attempt (AY/A) Calculator
Definition of Adjusted Passing Yards per Attempt (AY/A):
Adjusted Yards per Attempt (AY/A) is an advanced measure of passing efficiency that takes into account touchdowns and interceptions in addition to yardage and attempts.
The result is:
0
What is the adjusted yards per attempt for a quarterback who has thrown for 4000 yards, 30 touchdowns, and 10 interceptions on 500 pass attempts?
Formula Explanation:
The formula for calculating AY/A is: (Passing Yards + (Touchdowns * 20) - (Interceptions * 45)) / Attempts. This formula adds a 20-yard bonus for each touchdown and a 45-yard penalty for each interception before dividing by the number of attempts.
Detailed Explanation:
AY/A provides a more nuanced view of a quarterback's performance than standard Y/A by incorporating touchdowns and interceptions. The 20-yard bonus for touchdowns and 45-yard penalty for interceptions are based on statistical analysis of the relative value of these events. This stat gives a better picture of a quarterback's overall effectiveness and risk management.
Importance:
AY/A is crucial for evaluating quarterbacks as it balances the ability to gain yardage with scoring prowess and ball security. It's often considered a more accurate measure of quarterback performance than standard Y/A.
Historical Use:
AY/A was developed as an improvement over standard Y/A to better reflect a quarterback's overall effectiveness, including their ability to throw touchdowns and avoid interceptions.
Historical Context:
AY/A has gained prominence in recent years as advanced statistics have become more widely used in football analysis. It's particularly useful for comparing quarterbacks across different eras or offensive systems.
Limitations:
While AY/A is more comprehensive than Y/A, it still doesn't account for factors like sacks, rushing ability, or the quality of the quarterback's supporting cast.
Example:
If a quarterback throws for 4000 yards, 30 touchdowns, and 10 interceptions on 500 attempts, their AY/A would be calculated as follows: (4000 + (30 * 20) - (10 * 45)) / 500 = 8.1 AY/A.
Famous Examples:
Aaron Rodgers holds the NFL record for the highest career AY/A at 8.4 (as of the 2021 season).
Frequently Asked Questions:
What is considered a good Adjusted Yards per Attempt in the NFL?
In the modern NFL, an AY/A above 7.5 is generally considered good, while anything above 8.5 is excellent.
How does AY/A differ from standard Y/A?
AY/A takes into account touchdowns and interceptions, providing a more comprehensive measure of quarterback efficiency than standard Y/A.
Why are touchdowns worth 20 yards and interceptions -45 yards in the AY/A formula?
These values are based on statistical analysis of the average impact of touchdowns and interceptions on team performance and scoring probability.
