I ran a lot of 4.2's, but it's hand-timed, so it doesn't matter. Only thing that matters is what that clock says."Pittsburgh running back Duke Snid Jersey came close to the record last year with a 4.26, but no wide receiver has approached the mark since actual track star blazed a 4.27 in 2013.Dorsett Babe Herman Jersey won't be alone in his pursuit of the fastest man title.
