RB Efficiency: Who is the Shiftiest? Through 2 weeks


Good to see, as EPA per run play is soaring ahead of EPA per pass play, we are on top of this curve.

  1. Would you mind elaborating on how this graph shows RB efficiency or shiftiness and how it relates to EPA/play on runs and dropbacks?

    The graph doesn’t include broken tackles, presumably because that wouldn’t be shifty. But aren’t broken tackles an important piece of information about RB performance? However…

    The graph clearly evaluates a per-touch base, and in doing so mixes receiving and rushing plays. So we end up comparing apples (skat backs) to oranges (bell cows).

    Yet you feel confident to draw conclusions from this observation and relate them to EPA/P for run and pass plays, a completely different metric that obviously separates run plays from dropback plays, unlike the graph you’re drawing your conclusion from.

    Sorry, to me this is pure data dada nonsense for the sake of generating a graph that has Washington’s RBs in the upper right quadrant.

    Let’s be real: Kamara and Robinson have the same yds/touch. Does it matter that, in a two-game sample size, Robinson generated 0.15 more missed tackles per touch? It didn’t get him any further. Who cares how he got there? In fact, isn’t Kamara’s performance even more impressive given he generated the same yardage with fewer missed tackles?

    Dobbins and Ekeler have similar yards per touch. Are they comparable? Ekeler had 10 carries and 7 receptions, a 13% target share of our passing offense. Dobbins ran the ball 27 times, 37% BRKN+missed tackles per run(!!!), and had only 4 receptions for a total of 4 yards. You tell me.

    Don’t get me wrong. I like how we use our RBs. I like how they both execute. But this chart is about as lame and misleading as it gets.

  2. I think it’s really just who’s the best at breaking tackles in general through power or shifting around them either way still a good thing
