The Pro Football Focus grading system gave Johnson a minus-12.7 for the first half of the season, a plus-12.9 for the second half. Their analysis showed most of Johnson's struggles coming in the passing game, as he did things you might expect an inexperienced tackle to do - lunge with his head down, shoot his hands at the wrong time. In the run game, PFF graded Johnson plus-6.7 for the season, best among rookie tackles and 11th best among tackles overall. Kelly's offense is built around the kind of running plays Johnson seems best suited for, charging out to the second level with LeSean McCoy on his heels.
