This is a messed up story, but the idea that the NBA is rigged is patently ridiculous.
The refs are humans and are biased to crowd noise, and you can bet it harder to stand up to LeBron James screaming at you than Quinn Cook.
What evidence is there that they "actively encourage seeing it the home teams way?" What if a huge star is on the road, what's the call there?
Of course they want the bigger media markets to do well and competitive gameplay.
Do you think they're rigging it so Milwaukee or Portland is good? What about the 20 year run of the Spurs?
