Regular Season QBGOAT VI: Career Stats

Welcome. If you’ve been following along, you know that I’m in the middle of a series on the greatest regular season quarterbacks in NFL history.1 The first set of posts explored different ways to look at the top single seasons. Today, I’ll begin my first look at career stats. As always, I’ll be using Total Adjusted Yards per Play, my bread and butter stat, as my performance measure. If you’re not familiar, Total Adjusted Yards is a metric, expressed as yardage, that accounts for a…

Regular Season QBGOAT V: Index Scores and Abstract Value

I hope you’ve enjoyed following along in the GOAT quarterback series. Today marks the final look (for now) at single season statistics.1 Here, I’ll be discussing Index Scores2 and Abstract Value3, with Total Adjusted Yards per Play as the root metric. For the uninitiated, Index Scores are used by Pro Football Reference to normalize passing stats across eras. If you’re familiar with IQ scores, then Index Scores should make sense to you, as they’re basically the same formula. The metric is based on Z-scores (the number…

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…

Regular Season QBGOAT III: Hard Inflation Adjustment

Welcome to part three of my series on the greatest regular season quarterbacks of all time. In part one, we looked at the standard metrics, based on Total Adjusted Yards. In part two, we looked at those numbers prorated to the modern 16-game schedule. Today, I’ll be adding a hard inflation adjustment to account for the increase in quarterback usage rate as the league has evolved. After coming up with the numbers from the first two articles, we can then apply our adjustment for inflation.…

Regular Season QBGOAT II: Prorated Season Stats

Yesterday, I laid the groundwork for the “QBGOAT” series, providing the essentials for following the subsequent posts. Today, I’m going to build off that foundation by looking at the metrics from yesterday prorated to the 16-game season we know today. This should help put the quarterbacks of yesteryear on a level playing field with those of today. To prorate to the modern schedule, I simply multiplied every player’s total values (the last three columns in the table from yesterday) by (16 / scheduled team games).…

Regular Season QBGOAT I: Single Season Stats

To kick off the series on the greatest regular season quarterbacks of all time, I’ll start with the single season stats highlighting the most productive quarterback campaigns in history. In this post, we’re just going to look at the stats as they are; later on, we’ll deal with the expanded NFL schedule and the evolving nature of the position itself. As usual, I am going to measure quarterback output by efficiency (Total Adjusted Yards per Play) and effectiveness (marginal Total Adjusted Yards over average). I…

Yards From Scrimmage Monsters

Today I want to take a look at skill player production as measured by yards from scrimmage. I will look at top performers in standard yards from scrimmage, yards from scrimmage prorated to a 16 game schedule, and yards from scrimmage over multiple baselines. This isn’t meant to be a list of the greatest offensive players in history, but it will certainly shed some light on players who may have been underrated in the eyes of the masses. The methodology for these metrics is very…

All Time 53 Man NFL Roster

Sometimes when I am bored, I make football lists or rosters in my head (what is the all-time Steelers team, what is the current all-NFC South team, what is the all-time Hispanic team, etc.). Of all the whimsical thought experiments in which I have engaged, the one with the most decisions and revisions has been my all time 53 man NFL roster (with coaching staff). The purpose of building an all time 53 man NFL roster is not to simply pluck the best 53 players…
