Johnson is as tough as it gets at the point of attack, where he was able to consistently battle and fend off blockers who were much bigger than him. He plays with excellent contact balance and is almost never on the ground. His arms are short for the position at the NFL level and his overall mass is below average for an interior player, but he rarely looks overwhelmed by his opponent’s power or double teams. Johnson is a consistently productive interior prospect, but his lack of physical traits is likely to limit his draft slotting and will potentially force teams to see if he can continue adding weight to his frame without slowing down.
