What 5 players averaged 20 points and 20 rebounds for their ncaa career?

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.
