Kick-out to the near-sideline corner. B1 closes out on shooter A1. Compare each official's modeled view of the shooter's landing space at the marked instant.

Kick-out to the corner with a hard closeout.

No modeled obstruction from: Lead, Slot. Scrub the timeline to see how this changes.

Coverage context

Trail: same sideline as the corner, behind the play.
Lead: baseline, angle across the corner.
Slot: opposite side, long view across the floor.

Which modeled positions have an unobstructed path to the shooter's landing space at release?

Synthetic play, invented positions. Geometry only — not where anyone looked, whether a foul occurred, or whether a call was correct.

Original modeled position: Some sampled paths obstructed
3 of 5 sampled paths obstructed · blocker: B1
Alternative position: Drag the orange T marker, or focus it and use arrow keys (Shift = 0.5 m). Playback pauses; the original is kept.

Other actors are held at their recorded or synthetic positions. This comparison does not predict how play would change.
