who has the fastest 40 time in nfl
40-yard dash Auburn's Bo Jackson claims to have run a 40-yard dash with a time of 4.13 s.[6][7] A time of 4.18 run by Jackson within the same week added some support to the legitimacy of the times.[8][9] Texas Tech's Jakeem Grant was hand-timed by a New Orleans Saints scout as running a 4.10 in 2016, potentially beating Jackson's record.[10] Deion Sanders ran a 4.27-second 40-yard dash in 1989.[11]
