So what's the big picture here? We've suspected for years that football leads to brain trauma. Does that mean the NFL should shut down? Should they continue to operate as normal? There have been efforts recently to make the game safer for players, but the amount of concussions and injuries seen every season don't seem to be decreasing. Can you make the game "more safe" without drastically changing the game? Any game…
I'm only a casual watcher of football, but I think it would be possible to change the game. My non-expert impression is that the game has evolved over the years (and I could certainly be wrong) and incentivizing players to avoid causing head trauma by penalties seems like the way forward (above and beyond current helmet-helmet collision rules). Maybe adding shock sensors to the helmets to objectively measure impacts is another thing they can do.
It would be interesting to learn what they already do today wrt measuring the forces on the head's of players.
Personally I wouldn't mind at all if the game changes. I would be satisfied watching them play the equivalent of flag football - high level strategy and athletic clutch plays can still occur with a safer game.
