How you cover up players committing suicide and donating their brains for scientific research?
Those are unfortunate events that occur over the span of a players career. What REALLY needs to happen is for players to be educated on the long-term effects of what they're getting themselves into by playing pro football.
But that's going to be overlooked because of the dollar signs on a contract.
Want to know why? Because every NFL player thinks it can't happen to them. Ego.
These guys KNOW what they're getting into. Same with NASCAR racers. None of them think they'll ever be a victim of the "big one" until it happens and somebody loses a leg or a life.
If the commissioner wants to make the game more safe, he needs to take games off the schedule. Go back to a 14 game season, and shorten the games to 10-12 minute quarters.
But if you cut back on physicality of the sport, you may as well kill off the sport itself.
