Only two players in NBA history have finished a season with 2,000 points and 600 assists prior to turning 23.
These two men would be Oscar Robertson of the Cincinnati Royals in 1960, and Derrick Rose of the Chicago Bulls this past season. Rose is in some pretty elite company, considering “the Big O” scored more points over his 14-year career than any other point guard in the history of the league. Perhaps even more amazing than just the feat itself is the inexperience both players had when they both achieved it. Robertson managed to do so in his rookie campaign, while Rose put up these numbers in just his third year! Unsurprisingly, both men took home Rookie of the Year honors in their first seasons, though Rose happens to be the youngest in NBA history to be named the league's Most Valuable Player. However, if Rose ever hopes to be considered a greater player than Robertson, he may have to up his game a bit - the year after Robertson achieved this rare feat, he became the ONLY player in NBA history to average a triple double (30.8 points, 11.4 assists, and 12.5 rebounds) over the course of a season!
