A mid-range game could open up his and the San Antonio Spurs' offense
Johnson has made a name for himself with his aggressive straight-line drives to the rim. That said, teams have begun picking up on that tendency of his, and they've started countering his drives by having a defender attempt to take a charge or by placing a big man in the paint to contest his shot at the basket. As a result, Johnson leads the team in shots blocked this season with 66.
While it's definitely a good thing that Johnson is as aggressive as he is, he could be more effective as a scorer by developing a mid-range game. A pull-up jumper, a floater, and a euro-step could make his offense much less predictable, and in turn, make it more challenging for players to defend him.
A pull-up jumper would give him another shot option when chased off the three-point line, while a floater could be a higher percentage option for when he’s able to get closer to the rim but unable to get all the way there. If he had a desire to add that to his game, watching film on Tony Parker could be a good idea for him.
Additionally, a euro-step would allow him to side-step opponents and potentially avoid offensive fouls. By adding these skills to his game, he could become a more effective interior scorer rather than relying solely on physical drives to the basket.
