Profiling Week Winners

Soon after last fantasy football season ended, Rotoworld’s Evan Silva worked to add fresh information to his data set. With the new data, Silva looked at the past three seasons of weekly player performances and built “profiles” for the four key offensive positions in fantasy. These profiles detailed characteristics of top weekly finishers at each position. For instance, in his RB profile, Silva found that of the 51 running backs that finished as the top weekly scorer from 2013 to 2015, 92% handled 18 or more touches and 71% played on a team that was favored by Vegas. These data points constructed by Silva can be used as the backbone of any weekly lineup setting. There are no true guarantees in fantasy football, but if you are looking to score the top weekly DFS running back, seven times out of 10 he is on a team that is favored.


The weekly player profiles, if incorporated into your decision-making process properly, can provide small competitive advantages.  They also can become even more powerful and credible when the data set is expanded to more than just the No. 1 finisher of each week. I took Silva’s analysis a few steps further and expanded to include the Top 6, Top 12, Top 24 etc. at RB and WR. With this new information we should be able to not only validate Silva’s findings, but also reach new conclusions about factors that separate a good matchup from a great matchup. First I’ll jump into the RBs and then take a look at the WRs.

RB Scoring Landscape


The value this analysis can provide can be summed up in the following table:




This table highlights just how important it is to be able to make the right player decisions when constructing a lineup. Based on the last three seasons, even identifying a Top 6 RB in a given week leaves you missing out on eight points to the Top overall RB. Note that this point differential has been consistent over the last three seasons and is double the difference between a Top 6 and Top 12 RB. Season-long participants who make lineup decisions with fewer players at their disposal than in DFS might be more interested in just being able to start a Top-24 RB every week, which is worth 18 points on average. Season-long players can use the following RB profile to better their odds at making the right decision in this quest to start Top-24 weekly scorers.


The RB Profile:


In January, Silva created the following profile for the Top Weekly RB:


Accounted for multiple touchdowns: 42/51 (82.4%)

Handled 18 or more touches: 47/51 (92.2%)

Played on team that won the game: 39/51 (76.5%)

Played on team that was favored: 36/51 (70.6%)

Played at home: 31/51 (60.8%)

Faced run defense that ranked 15th or worse in DVOA: 38/51 (74.5%)

Faced run defense that ranked 10th or better in DVOA: 4/51 (7.8%)


With my expanded data set (and a few added categories), the profile shook out like this:




Since this is now a lot more data to look at in the table and it might be hard to digest immediately, I find this picture helps ease you into the right mindset:





I’d like to highlight a few things before digging into heavy analysis of the profile. First, it is important to keep in mind that winning in fantasy football is about gaining every little advantage you can. Some of the percentages might seem to indicate that a particular characteristic plays little significance in determining a good matchup. However, over the course of a season and over many DFS contests every small difference adds up to something significant. It is also important to focus your attention on predictive measures, i.e. the ones that are known prior to a game with near certainty. We know who is home, we know who is favored and we know what defense a player is playing against.


“Drop off” in the chart is the percentage difference between a Top 1 RB and a Top 6 RB. A higher “drop off” indicates a category that is more important. For example, a Top RB scored 2+ TDs 82% of the time, while a Top 6 RB reached 2+ TDs only 47% of the time. This 35% “drop off” shows how important scoring multiple TDs is to a running back’s weekly finish. The players included in the “All” data set are all viable fantasy players that played each week at the position. For example, looking at the table you can see that 91% of Top 6 RBs were under the age of 30, but also 91% of all viable RBs in the NFL each week were under 30, so age does not seem to have any material impact on weekly RB scoring. I define “viable” as either a starter or a player that averaged enough touches per game to garner actual fantasy consideration.


Key Takeaways from the RB Profile:




From 2013 to 2015, 82% of Top 1 RBs scored multiple TDs but only 47% of Top 6 RBs accomplished that feat. Scoring multiple TDs greatly increases a running back’s chances of being a Top RB, however it is very challenging to predict. It’s not often we have any clue going into a game that a player is going to score multiple TDs, but looking into red zone carries per week or goal line touches can be a good proxy for trying to use this data point in weekly decisions. Maybe this could even lead you to picking up LeGarrette Blount when it’s going to be “one of those Blount games”. Few backs actually score multiple touchdowns each week, as evidenced by only 15% of the Top 24 RBs each week scoring more than once. Hence, TD scoring is ultra-important in large pool DFS contests and should be a major focus of lineup construction.




A running back handling a large workload (of at least 18 touches) tends to score more than other RBs. More than 90% of top RBs handled the rock more than 18 times. The spread is quite large between Top 6, 12 and 24, indicating that a RBs workload is very much a determinant of being a dominant weekly performer. Still, two-thirds of Top 12 RBs were given these large workloads compared to only about one-fifth of all viable fantasy RBs getting 18+ touches a week. This tells you that these high-touch guys are scattered sparsely across the league and if you have one in your lineup he has a good shot at putting up a top performance for you.


From 2013 to 2015, there were 616 games played by RBs who averaged 18 or more touches per game over the season. When these RBs saw at least 18 touches in a game, they scored an average of 18.8 fantasy points per week. I see this as more important to season-long fantasy owners who should focus on volume if feeling obliged to draft the RB position early.


Passing Game Involvement


Top weekly running backs in PPR are catching a good amount of passes (much to no one’s surprise), with over 70% of Top 6 scorers getting at least three catches. From 2013 to 2015 there were 32 RBs who averaged at least three catches per game, and these are often considered the high-floor RBs in PPR. So while a RB doesn’t have to necessarily be a pass-catching specialist, the elite scoring backs tend to be involved in the passing game to some extent. Two-thirds of top 12 RBs caught 3+ passes, so the first RB you draft this year should be a guy that’s going to catch at least 50 passes this season.




We already know Vegas is helpful in determining viable fantasy options, but this analysis shows there is a good chance the top running backs in a given week are on home teams and/or favored teams. This is especially helpful because these factors are determined before the game is started. Furthermore, with the expanded data set we can see that while just over half of “startable” (Top 24) RBs are on favored teams, the Top RB each week was favored over 70% of the time. Simply starting a player because he is at home seems to be grasping at straws strategically, but a majority of top performers across the board are playing at home. On the other hand, only 44% of Top 6 RBs played in games with the over/under set at 47 or higher. These 47 points are certainly a high threshold (66th percentile) but it begs the question: do lower scoring games actually lend themselves to better RB fantasy production? This could have a lot to do with game flow (as Silva discussed) which is always tricky to predict.


Opposing Defense


About two-thirds of RBs that finish Top 6 and Top 12 are competing against a run defense outside of the top-15 according to Fantasy Outsiders' Run Defense DVOA. This is another predictive measure and is one of the most consistent predictors of RB success. You should not expect top RB performances from RBs facing teams with a top-10 run defense according to DVOA. In Silva’s weekly matchups column during the season, he focuses heavily on opposing defense ranks and my analysis supports the theory that sometimes player performance is less about the actual player and more about the opposition. (Note that due to the timing of my analysis, I only had access to year-end DVOA and not the weekly ranks which would be more ideal for in-season decisions.)


Combining the Factors


Combining all the takeaways from a study like this is powerful in identifying undervalued RBs in the draft, free agency and DFS contests. DFS players can apply the conclusions from this analysis in a contest with many contestants where it pays to go against the grain. Great things can happen when all the predictive measures come together at once: a RB who is home, favored, in a game with an over/under of at least 47, averages 18 or more touches and averages at least three receptions. There have been 38 RBs facing these conditions in the past three seasons and they averaged 21 points in those games with 14 of them scoring at least 25 points.


Now we jump to the WRs, which have garnered extra attention and have received a boost in value due to Zero-RB theory and the horrific outlier of last year’s injury-plagued season for the RB position. I expanded the WR data all the way to Top 36, since many leagues start three WRs or at least have a flex.


WR Scoring Landscape




Just like the RBs, the Top WR each week outscored a Top 6 WR by almost 8 points. The spread between Top 6 and 12 and Top 12 and 24 also remained around 4 to 5 points for WRs. So once again, the ability to identify between a good and great matchup is substantial.


The WR Profile:


For reference, here is the profile created by Silva:


Accounted for multiple touchdowns: 35/51 (68.6%)

Played on team that won the game: 35/51 (68.6%)

Played on team that was favored: 33/51 (64.7%)

Played at home: 28/51 (54.9%)

Faced pass defense that ranked 15th or worse in DVOA: 32/51 (62.7%)

Faced pass defense that ranked 10th or better in DVOA: 13/51 (25.5%)

Played in game with Vegas total of 47 points or more: 22/51 (43.1%)

Played in game that went over the Vegas total: 37/51 (72.5%)


Here is what I found when I expanded all the way to the Top 36 players:




For the more visually inclined out there:




Key Takeaways from the WR Profile:




It should be no surprise that scoring touchdowns is a big differentiator in elite fantasy performance. Touchdowns correlate with weekly WR scoring at over 70%. This particular analysis shows that 69% of the #1 weekly fantasy WRs score multiple touchdowns that week, while only 47% of Top 6 weekly WRs hit paydirt more than once. This 22% “drop off” was greater than any of the other factors I analyzed.


Only 5% of all WRs score multiple touchdowns in a week, so a massive advantage is gained when you start a WR who does this.  This makes the lack of touchdown predictability for WRs even more frustrating. Although it is even tougher to predict when a WR is going to score multiple TDs than it is for RBs, drafting WRs who historically are above league average in red-zone targets and red-zone TD conversion percentage is a good strategy. Think Dez Bryant. This is especially valuable in PPR leagues where most other drafters are focused solely on guys who catch a lot of balls, without focusing on red-zone production.




As was true for RBs, volume is important for WRs. In the last 3 seasons, 86% of Top 6 WRs and 76% of Top 12 WRs caught 6+ balls that week. Volume is easier to predict for a WR than scoring multiple TDs in a given week. In the last 3 seasons, 22 players have averaged 6+ receptions per game in a given season:





You’re probably not blown away by the names at the top of this list. They are mostly your obvious, consistent performers that are drafted highly every year. However, Brandon Marshall is criminally undervalued in drafts every season and so far this year is the 13th WR being drafted according to Fantasy Football Calculator. This should also be a reminder that we are all being deprived of the enjoyment of watching Josh Gordon and Justin Blackmon play football.




Team total is a really valuable predictor of performance for WRs. A team total is the implied expected points for a team as calculated based on the Vegas over/under and spread. About two-thirds of the top scoring WRs in a given week had a team total over 22.5 (which is the median team total over the last three years). Team total is a better indicator than over/under (from Silva’s analysis) as it takes into account multiple Vegas metrics and is more team specific. You can see there is very little variation in the WR profile across the columns for over/under, due to over/under not being as team specific as team total.


A helpful exercise to perform when constructing weekly lineups is calculating the team totals and focusing first on the players on the teams with the highest totals. Be aware that these players will likely be highly owned in DFS.


Playing at home does not seem to impact the performance of a Top 6, 12, 24, or 36 receiver, however, a majority of the top performers come from players on teams favored by Vegas, just as was the case with RBs.


Opposing Defense


A top overall WR was opposed by a defense outside of the Top 15 against receivers about 63% of the time and against a defense inside the Top 10 around 26% of the time. This spread is not nearly what we saw with RB where these figures were 75% and 8%, perhaps opposition matchups are less influential to a WRs performance. However, a Top 12 WR went against a bottom half defense over 60% of the time and against a Top 10 defense less than 25% of the time which is very close to the Top 12 RB percentages of 66% and 23%.


While Top WR performances have mostly come against defenses ranking outside of the-top 15 in overall pass defense by DVOA, it does not seem like opposing defense is as helpful in differentiating between a potential Top 1 or Top 6 performance and a Top 12 or Top 24 or even Top 36 performance. All the percentages hover right around 60% for this category, which makes it less useful for large tournament DFS players.


If You Learn One Thing:


If nothing else, let this tidbit be the one thing you take away from this analysis.


One unexpected finding of this study was that WR performance appears to be affected by a defense’s ability to defend TEs. From 2013 to 2015, 56% of all wide receivers went against a defense outside of the top-15 in covering tight ends, but only 51% of the top scoring WR performances came against these defenses.





Everything in this table seems totally normal and there is virtually no difference between the two rows, except for the first column. This is certainly not a mistake and not by random chance. It could be due to offenses throwing more to tight ends when they are playing against teams that don’t cover the TE position particularly well. There are only so many targets to go around for a single offense, so if a TE garners a higher % of the targets than usual in a game, the wide receiver’s opportunities decrease. This information can be especially useful when constructing a DFS lineup, knowing that a WR’s ceiling can be capped when playing against a defense that is poor versus TEs.
