Causes of NFL concussions

There are many great prices that are being paid by the problem of concussions in the NFL. It is creating major health risks for the players. The time we are in today is the most concerned we have ever been with health and safety for not only people but also players. The main causes are helmet to helmet hits on players. Another very big cause is the fact that concussions are completely invisible and cannot be seen. It is up to the player to take care of himself which most of the time the player decides to play through it so he doesn't lose his job or let down his teammates or fans.
