What would be a bigger shift in the product: replacing all of the owners with random rich guys or replacing all of the players with D-Leaguers and guys bouncing around Europe?
Neither can happen.
Both parts are needed.
The NBA can't replace the players.
The players can't replace the league.
Let me rephrase that. Imagine two hypothetical worlds. In one, space aliens force all NBA owners to auction off their teams to the highest bidders, who must replace all management. In another, space aliens kidnap all NBA players, and the owners are forced to hire D-Leaguers and players currently toiling in foreign countries.
Which one would create a greater shift in the product?
But that makes no sense. Because the owners are not auctioning off their teams.
No one is saying the owners are irreplacable. We are saying that the players need the LEAGUE. That goes well beyond the owners. It is the infrastructure, the marketing, the history, and all of that.
Again, players need the league, and the league need the players.
And I would argue that it would be a better product to have a bunch of replacement players playing on NBA teams, with NBA coaches, NBA marketing, NBA TV deals, and all that, then a bunch of great players playing in some gym somewhere with none of that infrastructure.
