Historical Total Adjusted Yards Averages

In preparation for my series on the statistical production of every quarterback since 1932, I thought it would be helpful to publish today’s post as a reference for what will follow. The three tables below contain the historical Total Adjusted Yards averages for every season in NFL, AFL, and AAFC history (98 league seasons in all).1 Normally, I measure value based on TAY/P relative to league average, multiplied by total plays. However, for this series I decided to measure performance versus a three year average…

Adjusted Scrimmage Yards

Adjusted Scrimmage Yards is not a new concept at The GridFe; I used the metric last season to measure offensive output from skill players. However, I have never given the metric its own post, so I decided to change that. Today, I want to take a look at the top single seasons and total careers, as measured by Adjusted Scrimmage Yards, since 1992. For those unfamiliar with the metric, the formula is: Rushing and Receiving Yards + Rushing and Receiving Touchdowns*11 + Rushing and Receiving First…

History of the Career Rushing Touchdowns Record

As a lover of football history, I enjoy writing about the evolution of the game and examining statistical achievements from a historical perspective. I’m also fond of looking at the progression of career records, as doing so can often give us a glimpse into the progression of the game itself. I’ve previously written about the history of the passing touchdowns, passing yards, and receptions records. Today, I’ll focus on the storied history of the carer rushing touchdowns record. The first ever Football Sunday in league…

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…

Career Total Adjusted Yards per Play Index Scores

Earlier this week, we looked at the top single quarterback seasons as measured by Total Adjusted Yards per Play (and New TAY/P) Index Scores.1 Today, we’ll take it a step further and look at career Total Adjusted Yards per Play Index Scores. For a full explanation of how I calculated the Index Scores, check out the previous article. The method I used to arrive at career numbers was simple and straightforward: Find the Index Scores for each season Multiply each quarterback’s season score by his…

Single Season Total Adjusted Yards per Play Index Scores

I recently posted the top single seasons in Total Adjusted Yards per Play (and New TAYP) marginal value and value above replacement. In my original article on marginal value, I found value by finding a quarterback’s rate stat relative to league average and multiplying that by his total number of plays. This time around, I was to account for the variance of the era in which a quarterback played. To do this, I’m going to take a page from Pro Football Reference and use Index…

Career Total Adjusted Yards Above Replacement

Yesterday, I discussed two different ways to use Total Adjusted Yards and its derivatives to calculate career value above replacement for each season. The explanation of the methodology is somewhat tedious, so I won’t besiege your senses with it again today. If you’re interested, the full breakdown is available in yesterday’s linked post. Today, I’m going to use the same model to find career value above replacement. There are two ways to do this: I can find each player’s weighted value per play and multiply…

Single Season Total Adjusted Yards Above Replacement

Last week, I unveiled the single season Total Adjusted Yards per Play (and New TAY/P) ratings for every qualifying quarterback season since 1992.1 In that post, I covered production and total value relative to league average. Today, I want to add a new wrinkle and look at value above replacement level. Replacement level is a well established concept in baseball, but it isn’t a very popular notion in football. Football Outsiders has done the most thorough and well-publicized work on the subject that I am…

Career NTAYP Since 1992

Yesterday, I presented the Total Adjusted Yards per Play (and the newer version, NTAYP) metrics for every qualifying quarterback season since 1992. Today, I’m going to take a look at the career numbers. Keep in mind that, since this study only goes back to 1992, it ignores the first sixty years of the NFL stat-keeping era, focusing instead on the past quarter century.1 From a practical standpoint, this means we can’t look at legends like Sammy Baugh, Johnny Unitas, or Roger Staubach. It also means…

New Total Adjusted Yards Per Play Since 1992

If you’re a semi-regular reader of the site, or if you follow me on Twitter, you’re probably at least somewhat familiar with Total Adjusted Yards per Play (TAY/P). TAY/P isn’t as advanced as popular metrics like DVOA and ESPN’s Total QBR, but it is my favorite stat to use because it is transparent, easy to calculate on your own, and backed up by research.1 It also compares favorably with the more popular, propriety stats.2 Not wanting to give too much credit to quarterbacks for the performance…
