Massive guy that uses his size well, and can engulf defender at the point of attack. Hard to get around in pass protection and does a nice job in a short area. Flashes potential as a drive blocker. Shows ability to get position when blocking on the move. Shows some ability to pull and get out on the second level.
Slow and lumbering. Slow into his pass set and struggles working against speed. Has poor footwork in pass protection. Lacks pop off the snap as a run blocker and comes out too high. Doesn't get as much push there as someone his size should. Doesn't do a good job using his hands, trying to bowl over defender with his shoulder, and doesn't try to lock onto linebackers on the second level just sort of getting in the way. Lacks any mean streak and sort of goes through the motions, rarely finishing his blocks. Gets overextended, bends his waist, and ducks his head. Struggles to adjust against the stunting defender and can get bull rushed despite his bulk into the quarterback. Misses assignments when asked to pull and doesn't take good angles to consistently get position.
Johnson will get opportunities because of his size, and the fact that he's a better athlete than most 360-pounders. But he's slow, lumbering, and plays lazily. Has a lot of experience playing inside and outside, but he is too slow to play tackle at the next level, and is not as physical a run blocker and guard as someone his size should be. Started 33 games over the past three years, working mainly at left guard as a sophomore and senior. Played most of his junior year at left tackle, but made the move inside in the second half of the season. Logged a total of 24 starts at left guard and 9 at left tackle. Also got some reps in a reserve role at center.
Some team may give Johnson opportunities early because of his size, potential, and the fact that he's a relatively good athlete for his size. But he plays with little fire or technique, and unless either of that changes at some point it's going to be tough for him to stick in the pros. Big, powerful players can sometimes get away with having inconsistent or sloppy technique because of their ability to dominate guys with their natural strength and size. But the problem with Johnson is that he rarely dominates anybody on tape, despite having the size to do so. His experience playing multiple positions means teams can try him at a number of positions, but his best role is going to be left guard because that will hide more of his flaws than any other position. Most likely Johnson will ride the pine for three or so years and then if he's improved and developed enough could push for a starting job. But unless he is a completely revamped player he's going to be exposed as a starter. Quick defensive tackles will eat him alive, and if he's not playing in a phone booth, his size will be negated due to slow feet and poor technique. Conditioning could be an issue and if he was to drop 25 or so pounds, I would like his chances. But more than likely, Johnson will be around for three or four years because his upside will net him opportunities, but eventually he'll wash out of the league because he's very limited.
Johnson has the sort of size and run blocking potential to be a factor at left guard. But he's too raw with his footwork and technique and at least initially would be worse than Justin Blalock on his worst days. If he was able to sit on the practice squad for a summer or two, and if Boudreau can teach him how to use his hands, and the strength coaches can get him into fighting shape, he might then have a chance to stick as a backup in Atlanta. But better players that require a lot less work will come along and eventually push him to the wayside.
Johnson is too raw and likely to take too long to develop to merit being drafted. Bring him to camp and hope he can surprise.
