Helmet-to-helmet hits

Many helmet-to-helmet hits occur every week in football from high school to the NFL. This issue has come to surface again with the NFL fining players who commit "vicious hits". 

I think as a paternalist and agree that we should protect athletes for many reasons, and of them is because of the new research on brain trauma from hits. 

I've always known about football players suffering concussions, but I did not know the effect of concussions/hits in the long-term. In the article, "How different are dogfights from football?", there's evidence that hits and concussion affect the brain and deteriorate it in the long-term. A protein Tau has been found in the diseased brains of football players; this protein shuts down neurons in the brain. Researchers such as Ann McKee that showed those brain that present this characteristic are from people suffering a type of dementia called chronic traumatic encephalopathy (C.E.T), which is caused by trauma/injury to the head. 
 
The article has a lot of evidence to relate hits to the head in football as a cause for C.E.T later in life on those players. I believe that hits can be dangerous and all that, but I don't think they are ever going to be eradicated from football, that's the nature of the game. 

I think that better helmets can help, but they are not going to prevent the effect of the collisions. People cheer at football games because it is a very physical game, they like the intensity of it. With physical games come injuries. I don't have a solution for this, but I do think some measures should be taken to prevent dramatic trauma to head.
