Bills’ NFL Draft Measurables: Trends at running back


If you watched the NFL Scouting Combine and were wondering if that burgeoning crush you’re developing is a player who fits the Buffalo Bills’ archetypes, then this series is written especially for you. This series will examine the Bills’ combine measurables by position during the Brandon Beane/Sean McDermott era. Previously, we laid out the format and the statistical composition, and you can find that here as an introduction to the IOL chart. For the rest of the series, there will be less of the math class talk, and a little more description of the types of players who exemplify those traits.


The chart below details the average scores for that year’s group of rostered players. “Rostered” is important because these are not just drafted players, but the accumulation of all the players who spend time on the roster, regardless of acquisition method. The combine columns are items you are already familiar with if you clicked on this article, and the last column you likely already know too, Relative Athletic Score (RAS). RAS was created by Kent Lee Platte (@MathBomb on Twitter), and it combines a player’s combine results and uses position-specific formulas to convert them into a score that can be compared between athletes. RAS uses a scale of 1-10, and a score of 10 is considered perfect.

The Range lines are the far extremes, plus or minus, that the Bills have rostered. For running backs, the historical averages for their height and weight are 70.1″ (5’10″) and 205.7 pounds respectively. The heaviest RB they’ve rostered is Mike Tolbert at 246 lbs, and the lightest is Marcus Murphy at 193 lbs. Motor Singeltary is the shortest RB they’ve rostered at 67″ (5’7″), and the tallest is Taiwan Jones at 73′ (6’1″). You get the idea.

The “SD” lines might be strange if you’re unfamiliar with standard deviation and/or didn’t read the first article, but the link above will get you there.

Compare the Bills’ average composite RB with Mockdraftable’s average for the position within the league as a whole:

To offer an idea of what some of the outliers look like, here are the far ends of some key RB measurables:

  • 40 Yard Dash: Fastest, Taiwan Jones, 4.33; Slowest, Mike Tolbert, 4.70
  • Vertical: Highest, Matt Breida, 42: Lowest, Marcus Murphy, 29
  • Shuttle: Fastest, Taiwan Jones, 4.08: Slowest, Senorise Perry, 4.43

One of the players who most typifies the Bills’ archetypes is LeSean McCoy,
