Who were the 3 men who averaged 20 points and 20 rebounds a game for an entire season?

I'm sure that one of them is Wilt Chamberlin
and one might be Kareem Jabbar and how about Elvin Hayes?

Hello PARTDUDE, you are correct that one of them is Wilt Chamberlain, accomplished this feat a number of times. Try and guess the other two again. I know you can do it.

Jerry Lucas and Bob Pettit

Excellant job CC!!

As I stated, Wilt Chamberlain accomplished this feat a number of times. Another center, Bob Pettit of then-St. Louis Hawks, did it once. The really amazing accomplishment was by Jerry Lucas of the old Cincinnati Royals. In the 1965 to 1966 season, Lucas averaged 21.5 points per game and 21.1 rebounds. What made his feat so notable was that he wasn't a dominating center. In fact, the 6 feet, 7 inch Lucas did most of his shooting from the outside.
