Frankfurt has the support that Bud Adams would die for. Constantly the NFL misread the market. They took too long to make moves. They protected themselves and their sport and money and didn't give Britball support at its height when it could well have made football a break-through sport. And here's the problem.
Football is expensive.
You can't deny it, pads, officials, and stadiums etc. You have to love the game more than you love your money. Owners aren't like that, football to them is a business. Over in the UK billionaires pour millions into soccer teams trying to make them invincible. Billionaires buy football teams and try and make them profit machines.
