Not strictly lay-up lines, as the shot type will not actually be a lay-up to begin with, but it is the same premise. The first in the 'shooting line' (red) will dribble in, and take a jumpshot from a specific mark. The first in the 'rebound line' (blue) will then run in and collect the ball, before dirbbling it back to the shooting line. Both players will join the back of the opposite queue (shooter to rebound, rebounder to shooter).
Rebounding is the least glamorous thing in basketball and one of the most decisive. It is also almost entirely a habit, which means it is entirely coachable.
Good spacing is only the start. The best modern offences teach players to attack the defence's rotations and play in a permanent 4-on-3 - here is how to coach that read.
The ball screen produces almost half of all professional offensive possessions, yet most teams still teach it as a memorised play. The modern approach trains the read - giving players a framework to decide based on what the defence does, not what the coach called.
