NFL draft profile...and you said he had no explosiveness and speed? Just wow.
Analysis
Strengths
Explosive burst and plays with suddenness. Elusive in tight quarters. Has lightning in his feet. Has hips and feet to stop and start without stalling. Rare ability on stretch plays to hit cutback lanes that other backs can't get to. Runs with patience and a well-timed burst. Has great feel as zone-scheme, one-cut runner. Changes direction without breaking stride. Courageous runner. Shows no fear when getting downhill. Strong-willed competitor with toughness. Has second gear around the corner and can erase the angles. Gets small(er) through the hole and runs behind pads. Fights through arm tackles. Regroups and balances himself after initial contact. Reads and sets up routes and adjusts to poorly thrown balls.
Bottom Line
One of the most explosive runners in college football during his time at Miami, Johnson doesn't need much of a crease to make defenses pay. His explosive quickness and elusiveness should help him adapt quickly to NFL speed. His feel and courage as a one-cut runner should earn him instant playing time. Johnson's lack of pass-protection skills and concerns about his durability could force him into a committee situation. He's perfectly suited for a role as a zone-scheme back.
