With hand timing, there’s little way to differentiate between the two — fingers clicking 0.2 seconds apart is hardly shocking.
But YouTube user Booyacash wanted to get to the bottom of it, so he put out this video that "confirms" Grant ran a 4.12-second dash.
If Grant really did run a 4.12, that would tie him for the fastest 40-yard dash in football history with Bo Jackson, whose time is more folklore than science. (Jackson was also roughly 75 pounds heavier than Grant.)
The fastest combine 40-yard dash time ever recorded is Chris Johnson’s 4.24.
It’s not shocking that news of Grant’s blazing time has created some fervor amongst Tech and NFL fans on Twitter.
