The new luxury tax rules have already demonstrated their restrictiveness.
The second apron taxes had been portrayed as a way to let small markets compete. In reality it is just another form of helping cheap & incompetent owners.
The Thunder would not have a market size issue if they did not move the team from Seattle. The reason mostly had to do with a new practice facility & renovated stadium.
The same can be said about the Grizzlies who left the third-largest metropolitan area in Canada (Vancouver) for a city with a third of the population. Why? Because the Grizzlies were given a brand new stadium.
Now the new relocation threat of Las Vegas has loomed over multiple teams, one of which is the Mavericks. Again a heavily populated city in a wealthy state that could lose their team to a small market, with a transient style population, because of the promise of a shiny new stadium.
The most ironic part of these restrictions is that all these NBA ownership groups are free market capitalists, who made their fortune on crushing and cannibalizing smaller companies.
