I've only been to Conseco Fieldhouse and Madison Square Garden. Out of the two, Conseco is cooler in the non arena part (hallway, entrance, dining, etc.). MSG is cooler in the actual arena part (cour and seating).
No one has averaged triple double in his career. Oscar Robertson did it for a single season in '61-'62 (the same year Wilt averaged 50.4 ppg) with 30.8 ppg, 11.4 apg and 12.5 rpg.
Wilt Chamberlain in '67-'68 averaged 24.3 ppg, 23.8 rpg and 8.6 apg.
Magic Johnson in '81-'82 averaged 18.6 ppg...
