I think of the NBA like the gambling industry. What are they really selling you?
Hope and speculation.
The illusion that you might really be the lucky one over all those other sad sacks. They do occasionally let the blind squirrel find a nut (lottery luck i.e. Spurs) but in the long run, the rigged system dictates that the house always wins.
The casino is the league and it's star franchises and star players that always gravitate to the same places.
Unfortunately I grew up in the proverbial one-horse town and my little brother was born the night the Blazers won the championship, so I'm hooked for life. But really I'm hooked in the sense that I play the cheap slot machines for the distraction value. I enjoy the entertainment and even admire the money making machine that the NBA has become, but in no way do I suffer under the delusion that the league is anything but big business.
