According to Forbes. The total worth of the NFL is 62,900,000,000. That would put it at 75 out of 211 countries GDP. That's just the value of the Franchise's. It does not include the wealth of players.
Think about that. The NFL is worth more than the GDP of over half the countries on Earth.
I would think that with that kind of money the NFL could find a way to address concerns that did not involve disrespecting the very thing that has given them everything they have.
