Players suing NFL over head trauma. Are they saying the league knew this was happening?

9. The lawsuits are more than that

One is the impact of concussions is better understood these days and your first sentence is one thing the lawsuits will find out. Another point of contention is how the league handled players w/ a concussion or any injury. Usually it was "get back out there". You can't deny that was the culture of the NFL and still is to some extent.

I remember in 2003 Denver was playing against San Diego during week 2. Plummer got injured, went to the locker room and came back out. It was said that he suffered a concussion. He finished out the drive in which they scored their third TD in the first half then Buerlein came out there. After the game it was revealed he actually had a tear or something in his shoulder but Shanahan claimed it was a concussion so players wouldn't target his shoulder. That is one obvious case where the player went out there (and when you consider it was claimed to be a concussion and still went out there and not be a problem (now it is) is a sign of how the league handled it when it came up). It was also the same week Shanahan packed the Broncos white jerseys which forced San Diego to wear the dark jerseys in September.

Also a topic is if/how will the league pay for former players with mounting medical bills and lifetime of memory, cognitive, emotional, & behavior problems due to the head injuries?
