Regular Season QBGOAT IV: Soft Inflation Adjustment

Welcome to part four of my QBGOAT series. In part one, I laid the groundwork with the standard metrics. In part two, I prorated for longer seasons in the modern era. In part three, I adjusted for the increase in quarterback usage in recent years. Today, I’m going to apply to soft inflation adjustment in order to avoid giving too much credit to the quarterbacks of a bygone era. Essentially, I’ll be applying a similar approach to the one from part three, but I’ll be using weaker multipliers in order to mitigate the sometimes alarming effect of converting 1940s numbers to 2010s numbers.

The methodology for the Soft Inflation Adjustment is simple:

  1. Find the total plays run (by quarterbacks only) in every league season.
  2. Find the total such plays for every three year span in history (year n-1, year n, and year n+1)
  3. Find the average plays per league game for every three year span.
  4. Find the average plays per game for the whole of history (34.7).
  5. Divide the historical average by each season’s average to find that season’s hard multiplier.
  6. Take the average of the hard multiplier and 100% to arrive at the soft multiplier.
  7. Multiply each player’s Total Adjusted Yards metrics by the soft multiplier for the season in which they played.

I’ll use Sammy Baugh‘s 1945 and Tony Romo‘s 2014 as examples:

Baugh’s total value over average was 1044. He played in the 10-game era, so that number is prorated to 1671 (1044 * (16/10)). The average QB plays per game for 1945 was 27.8, so Baugh gets a hard multiplier of 1.249 (34.7/27.8). When averaged with 100%, that drops to 1.124, which is his soft inflation adjustment. Thus, his final adjusted value is 1878.1

Romo’s total value over average was 830. He gets no benefit from prorating his season, given he played in the 16-game era. The average QB plays per game for 2014 was 40.9, making Romo’s hard multiplier 0.848 (34.7/40.9). After modifying that number to make the adjustment weaker, his soft multiplier is 0.924. Therefore, his final value after adjusting for era is 767 (830 * 0.924).2

Total Adjusted Yards: Soft Inflation Adjustment

This table contains data for every quarterback season meeting the following criteria: at least 300 plays, at least 1500 Total Adjusted Yards, or an absolute value greater than 500 in the “VAL” column.3 It is sorted by VAL but can be re-sorted as you like. Read it thus: In 1943 Sid Luckman had the modern equivalent of 425 plays for 4162 Total Adjusted Yards, good for 9.79 TAY/P. His efficiency was 6.79 better than average, 7.54 better than 75% of average, and 9.31 better than one standard deviation below average. This means his value above average was 2886, and his value above replacement was 3205 or 3956, depending on your method of finding the replacement baseline.

bert jonesAfter applying softer adjustments, the top four remains the same as it was after just prorating for season length. Luckman’s 1943 harbinger of the passing explosion sits atop the list. Peyton Manning‘s surgical 2004 campaign takes the runner up spot, while Dan Marino‘s legendary 1984 eruption completes the medal podium. And no list of greatest QB seasons is complete without Tom Brady‘s scorched earth 2007 performance. Bert Jones‘s 1976 MVP season knocks Aaron Rodgers‘s first such season out of the top five, and a Baugh masterpiece and three Otto Graham offerings round out the top ten.

We see an incredible, MVP worthy year from an Fouts sitting at eleventh. This is perhaps the most interesting of all the rankings, as the strike-shortened 1982 season was actually shorter than any other full season since teams began playing a standardized schedule. Despite playing in a modern era, all quarterbacks from 1982 receive a huge boost from the seasonal adjustment; in fact, with a 1.78 multiplier, they nearly double their value scores. I don’t know if this is fair or unfair.

I don’t necessarily like the idea of giving players credit for passes they didn’t actually throw or games they didn’t actually play, but I also think making adjustments is necessary for making comparisons across eras. This applies to all shorter seasons, not just 1982. That year, Fouts actually ran 351 plays; that jumps to 624 when prorate to 16 games and then falls to 612 when given the soft inflation adjustment. We’re basically adding 261 plays, at the same rate, to his score.4 Like I said in the last post, it’s up to you to decide how you want to weigh these variables. I’ll do the work and give you the numbers, and you choose what you like best.

The top 100 seasons comprise fifty different quarterbacks from 1934 to 2015. Unsurprisingly, Peyton Manning leads all players with six seasons in the top hundred. Otto Graham and Steve Young have five seasons apiece, showing that their prime years were as dominant as they come. Tom Brady and Drew Brees, statistical equals for most of their careers, both feature four top hundred seasons. Ken Anderson, heartthrob of stat-lovers everywhere, also has four such years.

If we focus on years instead of players, 1976 and 2009 feature four top 100 seasons each, tops of any year. Prorating for schedule and adjusting for inflation proves to give us what I think is a pretty fair split among decades: The 2000s have 19 highly ranks seasons, followed by the 1960s with 16, and the 1940s with 15. The 1980s and 70s feature 13 and 12, respectively. Only nine seasons represent the 1990s. That seems low at first, but I can’t think of too many great quarterback years that didn’t belong to a handful of players. The 1930s only feature two seasons on the list, but that’s not much of a surprise given the lack of great quarterback play early in league history.

The real curiosity here is the 1950s. With five Hall of Fame quarterbacks in their primes during the decade, you’d expect to see more near the top. Maybe it’s a design flaw, or maybe the fact that such a large portion of starting passers were Canton-bound talents made it harder to stand out, statistically. Alternatively, it’s possible that there really weren’t that many all time great seasons from the fifties. After all, there have been 1813 quarterback seasons in history with at least 224 plays (the NFL’s official minimum to qualify for rate stats), and only 80 of them occurred in the 1950s. Given that offensive production was higher in that decade than in either the preceding or following decade, it’s not surprising that only five of those eighty seasons were great enough to stand out.5

One last thing I must mention: I have not applied any sort of discount to AFL or AAFC players, so their seasons are treated with the same respect that 1977, 1984, or 2015 seasons are given. Obviously this is erroneous, but I am not quite sure how erroneous it is. I have done rigorous study to find weights for each individual AFL and AAFC season, but the punishments for playing in the lesser leagues seemed way too harsh to me, despite being theoretically accurate.6 Brad Oremland, a writer and researcher I respect tremendously, used multipliers ranging between 3 and 5 to each year beginning in 1946. He’d be the first to admit that the numbers were chosen based more on feel than on empirical evidence.

That’s part of the problem with these types of analyses. If we try to account for the strength of the leagues competing against the NFL, we probably need to account for other factors as well. What, for instance, is the difference in the NFL’s strength before and after the free agency era? How about before the big money era, when many college stars were more likely to play baseball or become schoolteachers than turn to the NFL?7 What about before the league was fully integrated; did Arnie Herber and Bernie Masterson really face the cream of the crop in opposing secondaries? Should we penalize players who thrived during World War II while many starters were protecting Amiens or storming the shores of some small land mass in the South Pacific? The Rams were forced to suspend operations, and the Steelers had to merge with the Eagles and Cardinals in successive seasons. Do we believe the NFL of this era measures up to the one we know today?

Sure, the rules favor the passing game now more than any other time in history, but today’s quarterbacks are also facing the biggest, fastest, and strongest defenders the league has ever seen. Today’s NFL is built on players with years of development from Pop Warner through the collegiate level. Medicine, nutrition, training, and scouting are more sophisticated than ever before. The talent pool from which to draw players dwarfs that of previous generations. Athletic feats that left crowds awestruck in the earliest years of the NFL are now commonplace. We often think we’ve reached the limit of what players can do, and we’re wrong every time. Sixty years from now, when many of us are frail and wizened (if we’re lucky), they might be talking about our era the same way. Maybe every quarterback will look like Steve Young and every tight end will look like Rob Gronkowski.8 The league and its players will evolve. History has proven this. How we respond to this, as people who love the game and are fascinated by its numbers, will likely demonstrate what we value when we analyze the game.

Join me next time as I conclude the single-season portion of the series and transition to career accomplishments. If you have any thoughts on today’s post, I’d love to hear them.

 

  1. That is much higher than his original value of 1044, but it is also significantly lower than the 2108 we got with our hard inflation adjustment. Also, to cite precedent, Chase Stuart employed a similar methodology in his latest Greatest QB of All-Time article.
  2. Note that, while this looks bad for Romo, his value when using the hard adjustment dropped to 704 for that season.
  3. The thresholds for plays, TAY, and VAL are taken after the normal stats are prorated to a 16 game season and then adjusted for the league passing environment.
  4. 1982 is also weird because the games missed came from weeks 3-10. That means quarterbacks, in general, only got the benefit of playing in warm weather for two games. The seven other scheduled regular season matches took place between November 21 and January 2. It’s possible that Fouts performed so well that year because he got to play six of those late season games in California.
  5. Also, note that 100 is a pretty arbitrary number, one which I only used because I grew up in a culture obsessed with things ending in zero or five. One hundred is no more meaningful than 99 or 101, nor is it any less arbitrary. Besides that, if I expanded the cutoff to 101, the fifties would get another season. If I expanded it to 106, yet another season. To 113, another season more. Fun with cutoffs.
  6. For the sake of example, let’s assume that the league was 85% as strong in 1960 as it is now. It was smaller, less lucrative, and didn’t yet feature the widespread steroid use brought on by Alvin Roy. Let’s also say that the AFL was much weaker than the NFL in its first season. I’ll be generous and say it was 50% as strong as the NFL in 1960. That means we’d have to apply a 0.425 (0.85 * 0.50) multiplier to compare the 1960 AFL to the 2015 NFL. While that seems reasonable and theoretically sound, most fans of AFL football would cringe at the results.
  7. This is the same era, mind you, that saw college teams compete favorably with professional teams. That would never happen today.
  8. Assuming the position still exists, that is.
