Has Any QB Ever Thrown a Perfect Game? The Elusive Passer Rating of Perfection
Yes, a quarterback can theoretically throw a perfect game, but the term “perfect game” in football doesn’t quite mean the same thing as it does in baseball, where it signifies a pitcher facing the minimum possible number of batters and allowing no one to reach base. In the context of a quarterback, a “perfect game” refers to achieving a maximum passer rating of 158.3. This rating is calculated using a complex formula that considers completion percentage, yards per attempt, touchdown percentage, and interception percentage. So, while a QB might not complete every single pass (although that helps!), they need to perform exceptionally well across all those key metrics to reach that coveted 158.3 mark.
Understanding the “Perfect Game” in NFL Terms
Unlike baseball’s absolute definition of perfection, a “perfect game” for an NFL quarterback is a statistical measure. It’s about efficiency and impact, not necessarily flawless execution in every single snap. The passer rating formula is designed to reward quarterbacks who are both accurate and productive, leading to high scores and, potentially, the holy grail of a 158.3 rating.
The Passer Rating Formula: A Deep Dive
The NFL’s passer rating is calculated using the following formula:
- (Completion Percentage – 30) / 20
- (Yards per Attempt – 3) / 4
- (Touchdown Percentage) / 5
- (0.095 – Interception Percentage) / 4
Each of these values is capped at 2.375 and can’t be lower than 0. The final passer rating is calculated as:
((Result of 1 + Result of 2 + Result of 3 + Result of 4) / 6) * 100
To achieve a perfect 158.3 passer rating, a quarterback generally needs to have a high completion percentage (around 77.5%), a high yards per attempt average (12.5 yards or better), a high touchdown percentage (11.875% or higher), and, critically, zero interceptions.
The Rarity of Perfection
Achieving a perfect passer rating is an incredibly rare feat. The high standards demanded by the formula, combined with the unpredictable nature of the game, mean that even the best quarterbacks have only accomplished it a handful of times, if at all, during their careers.
Notable Performances and Near Misses
Many quarterbacks have come close to the perfect passer rating, but falling short due to a single incompletion or an unfortunate interception. The list of players who have achieved the feat, while impressive, is relatively short. Even legends like Tom Brady, Peyton Manning, and Aaron Rodgers haven’t reached the summit as often as one might expect. The article mentions several quarterbacks who have accomplished the feat multiple times including Ben Roethlisberger and Peyton Manning who each have four, Kurt Warner and Tom Brady who each have three; and Craig Morton, Dave Krieg, Ken O’Brien, and Lamar Jackson who each have two.
Frequently Asked Questions (FAQs) About Perfect Passer Ratings
Here are some common questions about perfect passer ratings and quarterback performance in the NFL:
1. What exactly is a “perfect passer rating” in the NFL?
A perfect passer rating in the NFL is 158.3. It’s achieved by having a near-perfect combination of completion percentage, yards per attempt, touchdown percentage, and interception percentage. It essentially means the quarterback had an exceptionally efficient and productive game.
2. How is the NFL passer rating calculated?
The passer rating is calculated using a complex formula that considers completion percentage, yards per attempt, touchdown percentage, and interception percentage. The goal is to quantify how well a quarterback performed in a game.
3. How many quarterbacks have achieved a perfect passer rating?
While the article doesn’t provide the total number of instances, it notes that eight quarterbacks have achieved the feat more than once. It is important to note, the article also states that four of these games have occurred in the post-season.
4. Who are some of the quarterbacks who have achieved a perfect passer rating multiple times?
The article highlights Ben Roethlisberger and Peyton Manning (four each), Kurt Warner and Tom Brady (three each), and Craig Morton, Dave Krieg, Ken O’Brien, and Lamar Jackson (two each).
5. Is it possible to have a perfect passer rating without completing every pass?
Yes, it is possible, though highly unlikely. While a high completion percentage is necessary, the other factors in the formula, particularly yards per attempt and touchdown percentage, can compensate for a few incompletions.
6. What is the lowest possible passer rating a quarterback can have?
The lowest possible passer rating is 0.0. This requires a quarterback to have very low completion percentage (no more than 30%), low yards per attempt (less than three), a high interception rate (at least 9.5%), and no touchdowns, all while attempting at least ten passes.
7. Does a perfect passer rating guarantee a win for the team?
No, it doesn’t guarantee a win. While a perfect passer rating indicates exceptional quarterback performance, other factors like defense, special teams, and overall team performance still play a crucial role in the outcome of the game.
8. How often do quarterbacks achieve a passer rating above 100.0?
The article states that Tom Brady had the most games with a passer rating of 100.0 or above, with 156 games. This highlights how challenging it is to consistently achieve such a high rating.
9. What factors make it difficult to achieve a perfect passer rating?
Several factors make it difficult, including strong defenses, unpredictable weather conditions, pressure from opposing pass rushers, and the inherent randomness of the game. Even the best quarterbacks can have off days.
10. Is passer rating the only way to evaluate a quarterback’s performance?
No, it’s not the only way. Passer rating is a useful statistic, but it doesn’t capture everything. Other factors, such as leadership, decision-making under pressure, and ability to read defenses, are also important. Advanced statistics like QBR (Quarterback Rating) and PFF (Pro Football Focus) grades offer more comprehensive evaluations.
11. What are some other impressive quarterback records mentioned in the article?
The article mentions several records, including:
- Tom Brady holding the record for most career passing yards (89,214) and most regular season wins (251)
- Tom Brady having 33 wins versus the Bills (most career wins by a quarterback against one team).
- Ben Roethlisberger holds the record for most 500 yard performances in the regular season with three and most overall with four when including the postseason.
- Only four quarterbacks in NFL history have ever beaten all 32 of the league’s teams.
12. Which quarterback is considered by many to be the greatest pure passer?
Dan Marino is regarded by many as the greatest pure passer in NFL history due to his quick release, strong arm, and impressive stats.
13. Has any quarterback beaten all 32 NFL teams?
Only four quarterbacks in NFL history have ever beaten all 32 of the league’s teams. Patrick Mahomes becomes youngest QB to beat all 31 other teams.
14. What are some of the most unbreakable records in the NFL?
The article highlights the 1972 Miami Dolphins’ perfect season (winning every game) as a record that has stood for over 50 years. And also states that over the course of league history, no quarterback has ever lost to all of them.
15. Where can I learn more about the statistics and analytics of football?
