This story is interesting. Some former players are suing the NFL, regarding brain injuries they suffered while playing.
The NFL made a lot of money at the expense of former players. However, the players thought they were fairly paid at the time. The NFL has grown in size and revenue, leaving some former players feeling underpaid. The average player now gets paid a lot more than players 20-30 years ago, even when adjusting for inflation correctly.
Another important point is “Seriously? Getting hit in the head repeatedly is bad for you? Who would have ever figured that one out?” Football is a violent and dangerous sport. It’s silly to suggest that former players were not aware of the risks.
The legal system resembles a lottery rather than being based on merits. If you have a vaguely valid claim against someone with deep pockets, why not take a shot?
The NFL did make a lot of money at the expense of former players. However, it’s ridiculous to suggest that players didn’t know that getting hit in the head is bad for you.
