Also, the NFL DOES HAVE WAYS OF TRYING TO ASSIST POORLY PERFORMING TEAMS AND LIMIT TEAMS FROM HOARDING PLAYERS.

1. The Draft: Worst performing team gets the first pick, ie the best chance at the best rookie player, and then goes backwards from worst to best. Teams that make the playoffs are pushed to the end and the team that wins the Super Bowl typically goes last. 
   
2. The Salary Cap: Teams with absurdly rich owners can’t just throw all their money around, you can only spend so much money before the are capped off and can not give anymore expensive contracts to star players. You can’t buy a whole team of Pro-bowlers. It’s how smaller market teams or collectively owned teams (yes, the Green Bay Packers are owned by the people of Green Bay) to compete with the large market Patriots, Giants, and Cowboys.
3. Free Agency: Players get a 4-5 year contract when drafted, then can choose free agency to go where their skills will be most valuable, teams can not hoard all of their best talent forever and have to pick and choose.
4. Revenue Sharing: The rich teams give money to the poor teams to help them compete. Literally. Even the “cut throat, all business” sports leagues realize this form of “socialism” is needed to even the playing field.
5. Luxury Tax: The NFL doesn’t have this because of the Salary Cap, but other sports, like Baseball, do have a literal tax on teams that spend over a certain threshold. In the case of the MLB, teams that pass the threshold (in 2019 it will be $200 million) pay an escalating tax on every dollar above the threshold (first time is 20%, then 30%, then 50%). Mind you, this tax does not affect any team below the threshold so it is literally like AOC’s plan.
