I calculated the "Speed Score" for this yrs RBs.
Speed Score is Football Outsiders' metric for evaluating running back prospects. It's built on the simple idea that, because smaller backs tend to run faster than larger backs, we should be more impressed by a 4.5-second 40-yard dash from a 220-pound back than the same clock reading from a 170-pound back. As such, Speed Score incorporates a back's official time in the 40-yard dash with his weight to produce a measure of his speed given his size using the formula, (Weight * 200)/(40 time^4). As a guide, we consider a 100 Speed Score 100 as average, with anything below 80 serving as a giant red flag, and anything above 120 serving as a giant neon sign.
To put this in context of our previously discussed prospect: Knile Davis' 124.5 Speed Score is off-the-charts good.
Highest speed scores this yr:
Damien Williams 113.23
Jerick McKinnon 110.52
Tyler Gaffney 108.26
George Atkinson 108.24
