The NFL might be the teetering body of a dying deer about to fall dead; soon to be devoured by the vultures.
If this goes on for a protracted period, and some of these suits get legs, I wouldn't be surprised to see the league petition congress to protect it based on the public interest of having so much public money tied up in stadiums. Once that happens, there will be big taxes on tickets and the NFL will look a lot like the tobacco industry.
It could get very ugly.
