It’s pretty archaic reasoning. The brainwashing of the masses is an overly exaggerated and generic argument. This isn’t the 1980s. There will always be a segment of the population that believes or subscribes to racial superiority/inferiority. That much will always be true. But it’s not the “masses” anymore. It’s not the majority... unless you live in Florida or Texas maybe. And the NBA isn’t the NFL. The NBA has made a concerted effort to advance coaching and front office diversity. The most recent Coach of the Year is Mike Brown. The most widely regarded current best coach in the league is half Asian Erik Spoelstra. Darvin Ham is getting praised left and right for his adjustments and counters against Golden State. Just like Udoka last season.
If you were talking about the NFL, this argument might have some merit. The majority of their fan base is what you tried to describe. But not NBA coaching. Frank Vogel isn’t deified. And other than him and Bud, there haven’t been many other white coaches who “lucked into a championship” over the past quarter century. Almost all were proven, consistent winners. Phil, Pop, Riley, Kerr. Even Carlisle had a proven winning track record as a head coach. But he wasn’t deified either. Even after the le, Mavs fans bashed him for his stubbornness and unwillingness to evolve with the game. Spoelstra if you consider him white didn’t start to get much credit until after LeBron was gone and he started to overachieve with lesser talent. Nurse may be the one white coach who has been unjustifiably deified a little bit on these boards. But that’s their bad whoever did that. But every white coach who lucked into a championship? Nah son. Just not true.
Your take is bad. Really, really bad.
