Before we start shytting on ex-players, it's been well documented that the NFL didn't fully inform players of the long term effects of concussions and head injuries. And if a player did know about the effects, it came from non-NFL medical staff or after they were already suffering from other problems or death (See Chris Henry).
That's really what this case is about. NFL and their medial staffs didn't inform players, especially players from the 60s thru early 90s (maybe early 2000s), about the long term effects of head injuries. They used to let them go back in games even when they clearly shouldn't have been allowed to. As an employer, if you expose your employees to that risk without giving them the proper info then you open yourself up for lawsuits which is exactly what's happening. The players do have a legit beef.
Also the older generation players didn't make as much so they can't even cover their medical bills related to football injuries. And if the NFL knew about the long term effects then they should have every right to sue.
Do some of y'all not care about these dudes?
