Bro. A quick Google search tells me that the Premier League generated $6 billion, yet the NBA has topped $10 billion. A pure difference of $4 billion. I don't care about the future or what's going to happen, because it's all speculation and hypothetical. A quick fact search shows the NBA is far ahead of EPL in the current day, which is what I'm interested in.
The NBA has produced billionaires in Michael Jordan and Lebron James. Has the Premier League brand produced any billionaires? (Ronaldo doesn't count). NBA related merchandise is very popular throughout the world, especially the Jordans footwear. NBA player's on social media have a far bigger presence than your average Premier League players. The NBA has been extremely influential in pop culture, has the Premier League ever been influential in pop culture? The NBA Instagram page has more than 10 million more followers than the Premier League page.
It's actually disrespectful that you are comparing the Premier League with the NBA.
