Effect of Running Back Carries
on Future Production

Original Release: July 3, 2004


Marshawn Lynch had another big year last season, but a consequence of that season was his large number of carries (rushing attempts). He finished the year as one of the NFL leaders in that category with 301 rushing attempts. And when you consider the deep playoff run by Seattle on route to their Super Bowl victory last season, Lynch piling on even more rushing attempts on top of an already concerning number (Lynch had 65 playoff carries). Could that spell trouble in 2014? Read on! (See what the Docs recommend in their 2014 Fantasy Football Player Rankings)

In fantasy football, it's often difficult to predict which fantasy players will have a significant drop-off in production from one year to the next. This can yield devastating consequences for your team during your fantasy football draft, as you pay a premium price for a player just to have them crush your team with a very substandard season that did not warrant their high draft status. In this article, we will analyze yet another factor that can contribute to a disappointing fantasy season: The effect of Running Back Carries ( Running Back Attempts ).

Running backs are one of the crucial positions in most fantasy football leagues. While running backs can provide a consistently high source of fantasy points week in and week out and are in high demand on fantasy draft day, they are also prone to suffering a significant decrease in production after carrying the ball too many times in the preceding season. A running back's body is a machine, and, like all machines, they can only perform their function so many times before they must be replaced by a newer version (or sent in for repair). With that in mind, there are two measures (absolute and relative) to evaluate the wear and tear of running backs:

1. The absolute measure of the number of carries (attempts) a running back has had in the previous season (Table 1).
2. The relative measure in the increase in the number of carries from season to season (Table 2).

Both of these measures are indicators for a potential drop-off in production from one season to the next, and we have compiled two tables to help illustrate these points. Table 1 lists every NFL player that has experienced a workload of 370 carries or more in a season (through 2011) followed by their performance in the subsequent season.

  *includes massive playoff workload

The trend in the above table is clear and demonstrates drafting running backs with a large number of carries in the previous season is very risky business. Their fantasy football value will be extremely high due to coming off a huge season (after all, more carries means more opportunity to pile on stats and fantasy points), and overwhelming odds say they will not be able to justify that very high draft status and fantasy value in the following season. Through the 2011 season and out of the 24 running backs in the history of the league with 370 or more carries in season, in the very next season of play, (18) experienced a significant decline in fantasy production, (4) tore their ACL, and (6) effectively had their career ended. Only Eric Dickerson, Walter Payton, and LaDainian Tomlinson did not show any real effect or drop-off in fantasy point production in the season following their 370+ carry season. Stop and think about the names of Dickerson, Payton, and Tomlinson for a minute. They are arguably the best backs to ever play the game ("The best, Jerry, the best!"). The other 21 backs listed aren't exactly slouches and represent some of the creme of the crop in the history of the NFL.

Very high workload (carries) in the previous season equals trouble, and the cut-off for danger is approximately 370 or more carries in a year, although your measure for concern should start at 350+ carries. At 370 or more carries, the engine has overheated, and you should proceed with extreme caution when considering any back in this category from the previous season as a very high pick for your fantasy football draft. Between 350 - 369 carries in a season, the "check engine" light is on. That pace cannot be maintained, and there is danger of a breakdown. Backs like Curtis Martin, Earl Campbell, Emmitt Smith, and Terrell Davis were able to tote the rock in the 350 - 369 carry range without a significant drop in production in the subsequent season, while others like Herschel Walker, Stephen Davis, Ahman Green, and Deuce McAllister did experience a significant drop in production in the subsequent season. As such, if you see over 350 or more carries in a season, it should cause you to raise your eyebrow as a point of possible concern.

As mentioned above, while the absolute measure of the total number of carries in a season is a useful measure to critically evaluate running backs as potential let-down candidates for your fantasy football draft, the relative measure in number of carries from season to season is also an important consideration to keep in mind. Every running back is different, and their body is used to a certain level of abuse. If they experience a significant increase in carries from the previous season, it can be just as demanding (damaging) on their body as a season with a large, absolute number of carries. This relative, sharp increase in workload can also yield a breakdown in the subsequent season. To help illustrate this point, a few examples are provided in Table 2 below.

  *includes massive playoff workload

As shown in the above table, all the running backs listed had a breakdown after a large workload increase from the previous season (33% or more). As with any trend, it does not always hold as there are examples of backs that experienced a large increase with no ill effects (i.e. Priest Holmes in '01 and Tiki Barber in '02); however, it is something to keep in mind as another "proceed with caution" measure in your fantasy football draft. We would like to take a brief moment to also mention rookie running backs. Rookie running backs are generally excluded from consideration here provided they toted the rock as the primary ball carrier for their team in college. Yes, the NFL season is long and often you hear of rookie RBs discussing the added length (and abuse) of the NFL season, but the increase in workload from college is not typically as dramatic as many of the backs listed in the above table, and youth is also in a rookie running back's favor.

What running backs in my 2014 fantasy football draft had a high number of carries last year? Should I be concerned?
Entering 2014, NFL coaches have gotten wise to some of these statistical red flags, and a conscious effort is being made to make sure the total number of carries for a RB is watched closely. In the 2013 season, it was remarkable how low the overall carry total was for RBs in the NFL. Only two RBs even crossed the 300+ carry barrier: LeSean McCoy, PHI, 314 and Marshawn Lynch, SEA, 301. We can't remember a season where the carry total was so low across the board. Of the two players that did cross the 300+ carry threshold, we have to throw a little caution to the wind on Lynch. While his regular season carry total wasn't too hefty at 301, the deep run the Seahawks made in the playoffs to their Super Bowl win piled on a load of extra carries. If you include the number of carries Lynch had in the playoffs and add them to his regular season total, he amassed 366 total carries. That trips a caution flag with us, and something to keep in mind entering your 2014 draft. It's also another consideration when surveying the back-up RB situation in Seattle for late round sleeper candidates (RBs Robert Turbin and Christine Michael, although we favor Michael due to his higher talent level and upside. See more of what the Docs think about Michael, as well as other sleepers, in their Fantasy Football Sleepers).

What running backs had a big increase in carries last year? What are your thoughts?
On the increase in workload front, this particular statistical measure does catch RB LeSean McCoy in its web. McCoy saw a 57% increase in his total number of carries in 2013 compared to 2012. McCoy is a key center piece in Chip Kelly's new offense, and McCoy experienced the largest workload in his five year NFL career. However, when considering other factors like the number of receptions McCoy had, those were in line with previous years. So his workload increase was truly attributed to carries only without a noticeable increase in receptions as well. The net result when considering McCoy's age (26), 2013 workload relative to previous seasons in his career, and no significant increase in receptions in 2013 yields a RB that isn't quite as risky as he may appear. However, it is something to think about, and we wanted to bring it to your attention. If you draft McCoy and weren't already planning to do so, it would be a very good idea to handcuff his back-up to your roster with a later round pick. Think of it as life insurance. You hope to never have to use it, but if you do, you're glad it's there. Newly acquired RB Darren Sproles would be a prime back-up candidate to have on your roster with McCoy, but RB Chris Polk would probably see some more action as well if McCoy were to miss the time. Between the two, we favor Sproles as his tick up in action from a McCoy injury coupled with his already sound receiving skills brings the most fantasy sense to the table. However, we also offered Polk's name out there for those of you in deeper leagues wanting to cause the McCoy owner to sweat a little as you poach Polk during your draft. Never overlook the fun from the psychological warfare factor during your draft!

Another RB that experienced a significant increase in carries in 2013 compared to 2012 was San Diego RB Ryan Mathews. The new offense came calling last year, and Mathews saw his workload increase by 55%. Mathews does have a propensity to get hurt thus far in his young career, but in 2013 he was able to play in all 16 games for the first time in his four year career as well. As such, the workload increase last season was driven in part simply by the fact he played in all games and missed significant time in 2012 due to an injury. If you consider his workload in 2011 (222 carries), the increase compared to 2013 is below our 33% threshold. So in summary, we aren't as concerned about Mathews workload increase in 2013 compared to 2012, but it is something to keep filed in the depths of your mind. If nothing else, it makes his back-up, RB Danny Woodhead, a little more of an intriguing pick in the later rounds of your draft than he would otherwise be, but we don't see a direct hit on Mathew's 2014 draft value as he brings a lot of fantasy upside in the new offense.

In summary, there are two measures that can be used to indicate whether a running back will experience a drop-off in production in the following season: (1) The absolute number of carries for a running back in the previous season, and (2) the relative increase in carries from season to season. Nothing is more damaging to a fantasy football team than paying a premium price for a player in your fantasy football draft just to have them completely flop during the season and crush your team in the process. The absolute number and/or increase of carries required for a breakdown is different for different players. A few select players don't breakdown until they hit the upper 300's in carries. Others fall-off after a significant increase from the previous season. A few more take several years of heavy workloads (350+ carries per season) to shut down, and some just always seem to be injured. However, keep in mind these breakdowns don't necessarily have to come in the form of injury or missed games. Some of these "breakdowns" occur because a team added a young running back to take some of the burden off the veteran with high mileage. Even those incidences can be linked to carries because someone is putting the back on the shelf because a breakdown was inevitable. As far as a fantasy owner is concerned, a low scoring fantasy week is a low scoring fantasy week, regardless of how that was realized. As a general guideline, an absolute measure of approximately 370 or more carries in a season is a cutoff for danger, although 350+ carries is a starting point for concern, and a relative measure of 33% or more increase in workload in the previous season is also a cutoff point for danger. Naturally these guidelines are just that, guidelines intended to help reduce the risk of a poor fantasy football draft and increase the likelihood of a successful one. At the end of the day, it's all about stacking the fantasy odds in your favor on your draft day.
