Kansas Ref wroteNBA is legitimate Basketball ...
I'm sure that we can all agree that amateur basketball (high school, college) is entertaining, but the entertainment value is secondary to the the main purpose of amateur basketball, as a sport. Amateur basketball, especially high school amateur basketball, is not a business.
Whereas in professional basketball, both entertainment and sport are equally paramount. Professional basketball is, foremost, a business, an entertainment business that happens to involve a sport.
