Rebounding has always been and will forever be hard work.
When a player goes to the boards, he usually is being bumped and hit and pushed in the process.
Rebounding requires getting position and blocking out. More than just jumping up in the air to grab the ball, rebounding involves putting a body on an opponent and making sure that he isn't going to get the ball.
Without saying that "Rebounding is a lost art," I will state that fewer and fewer current players want to do what is necessary to be a beast on the boards.
Here are the 10 most dominant rebounders in college basketball history. As you go through the list, it won't take long to notice something curious about the time period during which these players played.
To create this list, average rebounds per game was the statistic used. Total rebounds were not utilized because that gives a distinct advantage to players who played more games. By looking at the per game average, we can "level the court" and see who really was most effective at hitting the glass.
