Johnson cuts an imposing figure, even on a major college program's offensive line. His massive 6-foot-6 and nearly 350-pound frame stood head and shoulders above his teammates', literally, during his first year with Louisiana Tech. The average height and weight for the other four members of the Bulldogs’ line was 6-3, 309 pounds.
The Mississippi native began his collegiate career at Copiah-Lincoln Community College, where he started at right tackle during his two years there, helping the Johnson then stepped into the right guard spot right away, and lined up for all 13 games in 2011. In 2012, he made the move out to left tackle for 2012 in order to utilize his height and length to replacing first-team All-WAC selection Kris Cavitt. Johnson was named second-team All-WAC.
Pure size gives him the power to dominate inside, but that also belies a fair ability to move behind the line and to hit second-level targets, who have little chance of beating his block once he’s latched on with his strong hands. Shows the flexibility to cut down defenders on the line and on the run, as well as the agility to take one or two defensive linemen with him down the line on zone run plays.
Foot speed is not elite in terms of pulling out in front of run plays at the next level, and NFL linebackers will be able to elude him in the run game more easily than their college counterparts. His height can also be an issue, at times, when he forgets to maintain his bend while trying to maintain leverage inside. Balance can be an issue in pass protection as he compensates for less than ideal foot speed. Pad level can be an issue.
Johnson played right guard in his first year at Tech as a junior college transfer. He moved out to tackle for his senior season, but is a better fit at guard. His size will likely have someone take a late-round flier on him.
Future Hall of Famer
A once-in-a-generation type prospect who could change how his position is played
An impact player with the ability/intangibles to become a Pro Bowl player. Expect to start immediately except in a unique situation (i.e. behind a veteran starter).
A quality player who will contribute to the team early on and is expected to develop into a starter. A reliable player who brings value to the position.
A prospect with the ability to make team as a backup/role player. Needs to be a special teams contributor at applicable positions. Players in the high range of this category might have long-term potential.
A player with solid measurables, intangibles, college achievements, or a developing skill that warrants an opportunity in an NFL camp. In the right situation, he could earn a place on a 53-man roster, but most likely will be a practice squad player or a camp body.
