Initial Scouting Combine Running Back 40 Times are in per CBSSports. See the table below for initiak Running Back 40 times. Some of these may be adjusted as we go back and look at the tape, so consider everything unofficial for now. Running back Dri Archer impressed scouts with a 4.26 40 yard dash time, the fastest running back time since Chris Johnson ran a 4.24 at the 2008 NFL Scouting Combine. Ka’Deem Carey of Arizona had a notably high 4.70 forty yard dash time which may cost him considerably in May. Lache Seastrunk, Tre Mason and Bishop Sankey turned in decent times but did not distinguish themselves from the rest of the 2014 Running Back class.
