Basketball Defensive Rebound
A defensive (or offensive) rebound can occur after any missed shot, including three-pointers, two-pointers, and missed free throws (unless it is not the free throw shooter's last shot).
Offensive rebounding is less common than defensive rebounding because if the offensive team commits too many people to get a rebound, they leave themselves vulnerable to a fastbreak opportunity.
Rebounding is considered a crucial part of playing defense. After all, working hard to force a difficult shot is useless if an offensive rebound occurs and the possession resets.
Getting Defensive Rebounds
The key to getting defensive rebounds is boxing out. This involves getting in a good position between an opponent and the rim to make a rebound. You can read more about boxing out in Basketball Boxing Out.
Bigger players often get more rebounds because they are closer to the rim. The best rebounders are also often larger and stronger, and therefore better equipped to box out.
Notable Defensive Rebounders
Some of the most successful rebounders in basketball history include Artis Gilmore, Wilt Chamberlain, and Kevin Garnett. Dominant rebounders in today's NBA include Dwight Howard, DeAndre Jordan, and Andre Drummond.
