Players . 2 and 4 run towarsds each other on meeting they both run of the pretend screen/defender and make them selves available to recieve the ball ( keeping receiving hand up as a target)

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.
