You make some great points too and I don’t disagree that 15 years for its demise is possible. I see that as a possibility for the whole System in general, which is in terminal decline, and for which the NBA is lumped in by proxy that it has the same folks running both.
The boomer point and the alienation point are tied together but perhaps we diverge on how. I don’t think White boomers have been the base for awhile now. In fact I don’t know one White boomer who’s an avid fan of the league. I think the White older base was replaced with blacks, jews, Asians and wigger White types. Those are who watches it in tv. Then to fill the stadiums, I think corporations buy a big chunk of season tickets and give them out to charities and employees. I know this is a common practice for the NY franchises.
I can’t remember the last time I’ve seen a White person over 30 wearing an NBA jersey. Yet I see DWFs in Yankees, Mets, Rangers, Giants and Jets stuff all the time.
PS - I do know 1 White boomer, of Greek persuasion, who is a huge basketball fan. Whenever I talk to him about the sport he always laments how the game has turned to “street ball”. He bemoans that every player carries the ball and that it’s too much “one on one” stuff. Then he often references how Arvydas Sabonis was one of the greatest players of all time, and how if he came to the NBA early in his career and avoided the injuries that slowed him down, he would have been recognized as such. Also, when the Olympics come around he roots for the Euro teams too, hahaha.
