Avery High Line is a different take on the ‘normal’ line out of bounds play. In most instances, coaches run ‘line’ against zone defenses. They also set the line with the low player near the low block.
In this version, the intent is to run this against a man-to-man defense. As you’ll notice from the diagram, the players also set the line starting at the elbow. With the high set and versus a man-to-man, the players have a lot of room to cut into open areas … especially if the defense is aggressive in denying and overplaying.
When the official hands the basketball to O3, O5 curls around and screens O1’s defender. O1 cuts to three-point line / wing area. After screening, O5 can roll to key area for potential open shot.
O2 dives to opposite low block and O4 dives to ballside low block.
O3 has multiple options here. O2 or O4 may be open on the hard cut to the basket. O1 may be open for the three-point or jump shot. And O5 might even be open after setting the screen.
