STRENGTHS: Lean, athletic build and is a legitimate NFL athlete with natural cover skills. Very light on his feet, showing great quickness and fluidity to turn and run with receivers when in man coverage, as well as excellent downhill burst back to the ball for zone.
He keeps his head on a swivel and doesn't panic when the ball is in the air, showing good timing on his leaps and the hand-eye coordination to pick off the pass. Johnson is aggressive and will bait quarterbacks, showing a terrific burst back to the ball.
He isn't an intimidating hitter but gets the job done,
generally wrapping the legs of ballcarriers securely. Has played inside in nickel as well as outside.
Johnson toughness belies his light frame. He started 41 game at Wake Forest, never missing a game due to injury during his collegiate career.
WEAKNESSES: In coverage, Johnson does show occasional over-aggression, getting burned on double-moves by speedy receivers. Good height and competes in jump-ball situations, but he may struggle in this regard against the behemoths playing receiver in today's NFL.
Where his lack of size shows up most is in run support. Needs to show more awareness and aggression in fighting through blocks, as well as the toughness to deliver forceful hits on the ball-carrier.
