sentences:  While several players who have entered the league out of high school have become successes (Kobe Bryant, LeBron James, Kevin Garnett, Dwight Howard, J. R. Smith, Amar'e Stoudemire, Jermaine O'Neal, Rashard Lewis, Tracy McGrady, and decades ago, Shawn Kemp and Moses Malone), others have been relative failures (for example, Ndudi Ebi, James Lang, Kwame Brown, Sebastian Telfair, Eddy Curry, Robert Swift, DeSagana Diop).Those in favor of an age limit made the argument that players entering the league out of high school did not know the fundamentals of playing professional basketball and also were not mature enough to handle playing in the NBA.Proponents of the age limit included Michael Wilbon, who argued that it was important for young players to get an education.
