Football is symbolic war. It is the closest sport to war, without arms. We send 18 year old kids to die, to defend our country. Question is, do we want to symbolize this in a sport in which there is the possibility of serious, life-long impairment? Apparently we do.
The solution may be in helmet design. In the event of a fall off my horse to land on my head (which could be at least a force equal to what any football player experiences), I wear a helmet which disperses the force of the impact to protect my brain (or what is left of it) from injury. This is accomplished by a layer of highly compressed insulating material, EPS, which is comprised of beads that burst when struck and are crucial in absorbing and dissipating energy from an impact.
I haven't seen the inside of a football helmet since I was in high school, although I suspect it is still just some type of cushions to soften blows. Clearly not enough. The energy dispersing helmets are $600 a pop, and lose their capacity to protect after a significant impact, so need to be replaced. However, what is more important, providing a different color helmet for each game, for some kind of marketing image or replacing with a quality helmet to protect head injury, that will be more expensive? With all the money being made from college football for almost everyone except the players, this should be a no brainer.
