How to Project RBs: Part 2

How to Project RBs: Part 2

rotogrinders misc fantasy football math

Projecting players’ scores is what Fantasy Sports is all about. There are a variety of methods that allow you to wind up with an accurate projection for any given player or players, but let’s face it, if you don’t have any method for projecting players’ output, then you’re probably not going to be a long-term winner. Even if you are making a killing each week utilizing the ‘feel for the game’ approach, projecting with stats might help you better understand how you are making those projections. Even if you are projecting based on ‘feel for the game’, you are probably still doing a bit of math and stats in your head in order to back up your guesses. In Part 2 we finalize an approach I use for Weekly NFL Projections.

Jacobs in the Top 10?

After hearing the news that Brandon Jacobs will start this week, it’s clear Tom Coughlin was reading Part 1 of this series, and noticed the Average Yards Per Carry table. I kid. We all know that Bradshaw fondness of fumbling this season is the main reasoning behind his demotion, but the timing of this switch is a bit precarious for moving forward with these projections in Part 2 since it effects two of the 10 players mentioned in this piece. For the sake of example, let’s assume that the Giants were planning to use both of their Running Backs this week as they had in the past to keep it nice and simple.

Percentage of Workload – Step 2: Percent of Team’s Carries

Percentage of Workload – (APG/Team’s Total APG), or as I am going to insistently attempt to coin, POW. POW is extremely important for Running Backs. A top RB will get many more touches per game (often around 20) than a top WR (often around 6). This makes an RB’s output much more consistent, in general, than WRs from week-to-week. A higher POW often means a player’s ceiling is higher, because they will have more opportunities to produce. Below are the same RBs from Part 1’s YPC, APG, and POWs.

Goal-Line Power – It doesn’t matter what site you are playing, touchdowns are much more valuable than yardage. The Goal-Line Power factor (we’ll call this GLP) in the table below is the:

Average of [(Amount of Goal-Line Carries Per Game / RB Average) + (Total Rush TDs / RB Average)]

This represents an RBs knack for finding the end-zone in their current offensive system. In this case, RB Average will be calculated from the same pool of RBs (those with at least 50 carries), which makes the RB averages 4.1 for GL carries and 3.64 for Rush TDs. When doing this on your own, you’ll want to use the field-size from which you would readily roster players from to calculate any averages. Doing the math gives us the following for GLP:

Running Back YPC APG Team APG P.O.W. GLP
Jamaal Charles 6.1 13.9 34.1 40.8% 0.28
Danny Woodhead 5.6 7 26.6 26.3% 0.53
Arian Foster 5.2 19.4 26.0 74.6% 2.99
Darren McFadden 5.2 18.4 31.7 58.0% .67
LeSean McCoy 5 14.6 27.9 52.3% 0.94
Brandon Jacobs 5 7.8 30.6 25.5% 1.42
Chris Ivory 4.8 12.6 24.8 50.8% 0.64
Tim Hightower 4.8 9.1 19.6 46.4% 0.66
Ahmad Bradshaw 4.7 18.5 30.6 60.5% 1.05
Adrian Peterson 4.6 21.1 27.1 77.9% 1.94

Defensive Matchups and Initial Projections

Here’s where Ray Lewis reminds you that Tom Brady and the QBs get all the attention. Don’t forget about the DE-FENSE! There’s 11 guys on that side of the ball too, and they each have control on the outcome of the game. Since, in the fantasy sports world, defenders come lumped in as one-unit, it’s easier to pull their stats. Each week, I like to take a look at NFL.com’s Stats to work the defensive Rushing/Passing numbers into my projections. Once we have all of the stats from defense to formulate our Rushing Projections per player, I like to:

Running Back Season Average P.O.W. x Yards Alwd / 10 GLP x TDs Alwd Def. Projection Weekly Projection
Jamaal Charles 9.68 43.0 0.229 5.67 7.68
Danny Woodhead 5.72 34.35 0.53 6.62 6.17
Arian Foster 17.29 77.21 1.085 14.23 15.76
Darren McFadden 11.97 65.37 0.365 8.73 10.35
LeSean McCoy 10.9 40.80 0.769 8.69 9.80
Brandon Jacobs 6.9 28.61 1.548 12.15 9.52
Chris Ivory 6.65 59.59 0.349 8.05 7.35
Tim Hightower 6.17 49.56 0.360 7.11 6.64
Ahmad Bradshaw 11.70 67.88 1.145 13.66 12.68
Adrian Peterson 13.91 102.05 1.057 16.55 15.23

Other Factors

Before making the projections final, there are ‘Other Factors’ I like to cover:

(Rec. Yards Per Game / 10) + (Rec. TDs Per Game X 6).
Note: If you do PPR, you will need to factor that in as well.

Final Weekly Projections

So we’ve finally got all the information we need to project our 10 RBs this week. This may look daunting at first, but once you get the hang of it, you can do these projections for all of the players in under 30 minutes in Microsoft Excel. This is a great starting point to project your players, and as you get a better feel-for-the-game, you can adjust your projections accordingly.

Factoring in the ‘Other Factors’ to the Projections above, I’ve calculated my final weekly projections for the 10 players below (now including receiving, non-PPR):

Running Back Weekly Projection Rec./Other Factors Week 12 Projection
Jamaal Charles 7.68 4.16 11.84
Danny Woodhead 6.17 3.31 9.48
Arian Foster 15.76 4.38 20.14
Darren McFadden 10.35 4.42 14.77
LeSean McCoy 9.80 4.41 14.21
Brandon Jacobs 9.52 0.59 10.11
Chris Ivory 7.35 -2.50 4.85
Tim Hightower 6.64 1.11 7.75
Ahmad Bradshaw 12.68 1.97 14.65
Adrian Peterson 15.23 3.57 18.8

Ceilings and Floors

The last point to discuss, is to analyze Ceilings and Floors. In a lot of instances, you will find that your projections wind up being very close between two players and you can’t decide whom to choose; this is when Ceilings become very important. Ceilings are predominantly determined by a player’s ability, as mentioned in Part 1, and they are also a sign of consistency. If your projections have two players coming in at about the same projection, you want to choose the player who is capable of breaking the big plays ( YPC ), the player who will get the most touches in the game ( POW ), or both. I am mentioning floors to be technically sound, but to be honest, if you have to consider a player’s floor, you should not be selecting them. By first, projecting your players based on stats, then choosing the players with the highest ceilings, you’ll certainly see a dramatic increase in your results.
