Simpson’s size and length are impressive, and there are flashes on tape, but there is still a lot of work to be done before he could be expected to play in an NFL game. Waist-bending hurts his balance, and he doesn’t have the foot quickness to mirror and match active NFL rushers. When he throws independent hands with timing, he can stall rush plans quickly and he’s good at keeping his hands active to stay in the fight. He won’t create much drive leverage as a run blocker, but his size helps to shield off defenders when his positioning is right. Teams will need to decide if they have the patience to continue a developmental pathway for him.
