This is a simple but deadly paint-pressure play. The goal is not to run the defense around. The goal is to drive the ball directly into the post. You create just enough movement to make the defense talk, then: #5 seals | #4 delivers | The paint gets punished.
Sometimes the best tactic is pure physics. By removing the secondary rim protector and creating a momentary distraction with the cutter, you turn the possession into a 1-on-1 wrestling match that your Big Man is designed to win.
