Wilton Norman Chamberlain He led the NBA in scoring seven consecutive years (1959 - 65) and in rebounding 11 times. He ranks first in career rebounds (23,924) and career rebounding average (22.9 per game). Bob Pettit averages 20 ppg and 20rbg in 1season. Jerry Lucas averaged 20ppg and 20 rpg 2 different seasons!!!
A surprising one I know for sure is Happy Hairston, approx. 14.5 ppg and 10.3 rpg in over ten seasons. Wilt, Hakeem,Bird, and Moses Malone all averaged double-doubles(points/rebounds in each instance) for their careers.Magic and John Stockton did with assists and points. I am sure that there are others that averaged double-doubles for their careers.
Clyde Drexler, John Havlicek, and Oscar Robertson
Malone averaged 14.9 points and 8.9 rebounds as a rookie.
i believe Julius erving and Dennis rodman have achieved this feet
Three players were able to score at least 20 points and 10 rebounds per game. 1) Chris Bosh 2) Zach Randolf 3) David Lee

LeBron James no doubt about it. He averaged more points, more assists, more rebounds. And he plays SF? Hah.
