If Elmore Smith of Kentucky State College/University, who averaged 21.6 ppg and 22.7 rpg in 1968-1971, isn't on your list, it's bogus. He is the only player on the NCAA Top 5 Total Rebounding List who only played three years, including his collegiate Basketball record 799 in 1970-1971 season.

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.
