The Good: Massive is an understatement when talking about his size. Showcases a sudden first step off the snap and has very good power in his lower body. Engulfs defenders at the point of attack; when he gets his hands on you, it's over. Showcases smooth feet and coordination in pass protection and offers some right tackle versatility. The Bad: At times doesn't always move his feet on contact and simply leans on defenders. Needs to keep his weight under control; played at 360 pounds at LSU but weighted 382 at the Senior Bowl.
Positives: Has rare size with a huge, big-boned frame, natural girth, huge hands and rare-sized, 361/2-inch arms. Good strength and can smash defenders off the ball, smothering them when he can latch on. Negatives: Not agile. Too big and has struggled to control his weight - has fluctuated close to 400 pounds. Lacks the foot quickness and agility to handle speed - can be outquicked by smaller defenders. Struggles to pull, maneuver in space and strike moving targets on the second level. Can not easily sustain. Not a finisher. Questionable football intelligence and instincts. Is late to recognize the blitz and react to stunts. Does not play smart. Marginal stamina. Summary: A straight-ahead power player with limited agility and lateral quickness, Johnson would fit best with a team that prefers heavy mashers such as the Eagles, Cardinals or Cowboys. Is built more like a tackle than a guard but needs help on both sides to have a chance. Grade: Mid-round talent.
