In the recent past, Johnson has been criticized by analysts for taking his game too far away from the basket. However, that wasn't the case against either Lexington Catholic or Lanier (MS), as Johnson did all of his work in the paint (The shot charts prove the point).
Though Johnson has an effective outside jumper, he's most dangerous around the basket where he can use his athleticism on the offensive boards and his strength to score on easy shots around the tin.
Here's a look at Johnson's offensive performance against Lexington Catholic. You'll see he was extremely efficient, making 5-6 shots from the floor. Also note, that all his makes were from close range and inside the paint.
The thing about Johnson is that while he doesn't take a lot of shots, when he does they're probably going in the basket. In two games at the Hoop Fest, Johnson made 14-18 shots from the floor and all but one came inside the lane.
Against Lanier, he showed a nice touch to 12 feet and threw down a one handed jam off an offensive rebound over some people in the paint.
He's clearly skilled enough to make an immediate impact on the college level next season. If he sticks close to the hoop he's very dangerous on the court.
