It sounds ridiculous but this is a legitimate problem facing the NFL moving forward. While there are many more billionaires today then there were 20-30 years ago, they mostly have "only" $1-2B, which is a ton of money but nowhere near what you need to buy 100% of an NFL franchise. Terry is in better shape than a lot of owners, especially legacy ones like Mike Brown or Mark Davis whose wealth is all just the team itself, and are rapidly finding themselves struggling to have enough cash just to put the guaranteed money on big contracts into escrow.
Get ready for a future where teams are sold to private equity companies instead of individuals, since at the rate team values are inflating nobody except Elon or Bezos will be able to afford a team. The number of "super" billionaires is very limited.
