Rebounding isn't dependent on length, verticle jump, or height. Rebounding is about will, strength, quick jumping, positioning, and reading shots. Some players just seem to stick to the guy blocking them out. Others just squirm around and find position. Rarely are rebounds (not tip ins) made above the rim. So how high you jump doesn't matter. It is how quickly you jump or reach for the ball. Many of the best rebounders were not the tallest or most athletic players. Barkley, Rodman, and Wallace were never the tallest, longest, or most athletic players.
