The players are getting bigger, and the physics just don;t work; a human body is just not designed to absorb those impacts repeatedly. The worst part of it is that is doesn’t have to be a cheap shot, just a run-of-the-mill play.
I agree that football will end because of all those litigations.
The Northwestern college players are trying to unionize and asking to be paid. It may end college football as we know it as well.
If we asked any player if he would stop playing football, even with those debilitating injuries, if he considered the injuries vs the millions of dollars they get paid, they would probably chose pay.
