That’s right, Jackson, the player ‘analysts’ scouted as a running back or wide receiver has set one of the highest marks in NFL history twice in his sophomore season.
He set his first perfect QB rating against the Miami Dolphins in a dominant fashion. Jackson went 17/20 passing for 324 yards and five touchdowns.
