Too often I see zero players going for the boards when the shot goes up. Players need to have a sense what is going on with their team and what position they need to be in every second on the court. Coaches must make sure, in practice, that at least 2 are in offensive rebounding position on every play. Defensive position, a position to run and win a 2 step race, involves being on the balls of the foot, knees bent, back only slightly bent. No matter how talented, each player needs to practice basics.
Many coaches laugh at fundamentals at the expense of the team, each player, and even their job.
With a little enlightenment, sensible practices, coaches could work what they would consider miracles. See my entire book for the solution. Looking is the most important. Hopefully I'll talk about this more in another article. For now, here is a simple description.
