You need to check how you are coding your answers. I typed in Michael Jordan, Kobe Bryant, Larry Bird, Julius Erving, Patrick Ewing, Bill Russell, Tim Duncan, Charles Barkley and Elgin Baylor (not "Bayler") and got nothing. But at least you're not a crank--when it didn't accept Michael Jordan then I figured we were dealing with someone out of touch with reality, which I'm glad you're not. Finally, it's Kareem Abdul Jabbar, Dave DeBusschere, and Alonzo Mourning.
Glad you didn't include Chamberlain like most people would have. Little known fact is that Chris Mullen when he was 17 played Wilt one on one and beat him 30-4.
