The phrase "phone booth guard" was made for Johnson thanks to his wide, girthy frame and immense playing power. Johnson has experience at tackle, but he's clearly an interior blocker on the next level. He has knock-back pop at the point of attack with the ability to win the block in a test of strength. In space, his limitations become obvious. He'll need to fit into the right scheme that takes advantage of what he does well and diminishes the athletic limitations. He has a ceiling of starting guard in the NFL, but his ability to deal with the athleticism of NFL defensive linemen on all three downs is a concern both as a run blocker and in pass protection.
