WRs, QBs and RBs run and drill today. The WR/RB speed drills are where the money is really made and lost at the combine.
Speed Score ratings for the top RBs
Speed Score is 40 time adjusted for weight, from FO like all my favorite stats. It's (200*Weight)/(40 time^4)
Significantly under 100 is a red flag, average adjusted score of all running backs is 98.5; for all drafted running backs, it's 102.4; for all running backs selected in the first round, it's 112.1.. Link
