In the NFL, players basically try to kill each other for money. A lot of people think this is wrong or bad or needs to be stopped, controlled, or reigned in. It doesn’t and it shouldn’t. The guys who play are adults and the people who pay are adults. It’s all voluntary. Nobody gets hurt who doesn’t volunteer for it. And it’s not like the risks aren’t known in advance, especially today. Let them play and let us pay and let’s all be happy.
An example of a player who decided it wasn’t worth it and quit. That, his decision to voluntarily leave a game, a profession, he voluntarily played, is the adult thing to do.
