The market dictates that Bronny is worth the money.
Why? Because the NBA is an entertainment industry, not a meritocracy industry. People will tune in to watch Bronny pass to his dad for 3 minutes a game before they'd tune in to watch an eastern conference 2nd round playoff game. Do I think it's still hilarious? Absolutely, but I haven't taken the NBA serious in over a decade.
If the NBA knew that midgets would earn more sponsors and viewers than what they currently have, you better believe they'd draft midgets each June instead of 6'8" athletes.
