The players are not innocents amongst the wolves. Status and money make it seem worth the risk of injury so they suit up and roll the dice.
Do you really think back then those players knew what was in store for them once their playing days were over?
When I hear about this kind of thing I can’t help but think of Lyle Alzado (who did not commit suicide).
The use of steroids (which was pretty much 100% in the 70’s) led to all kinds of health and mental issues. I am not saying this guy used, but if not he was the only besides kickers who didn’t.
That combined with the low technology and misunderstanding of concussions led to this tragic end (IMHO).
Prayers for his tortured soul and his family.
