I think concussions in sports is a major issue now and even more so into the future. Although we all like seeing pro athletes do what they do best, it doesn't mean its right. I will be the first to say their is nothing better than a huge hit in hockey or Football and the list goes on. The problem is were sitting on our couches watching this happen not thinking of the consequences for the players. These huge hits that lead to concussions have shown in research to have long term damage to the athletes. So although it may not show its self right away and the athlete may return after sitting out a few games, it still doesn't change the facts. Down the road those athletes lives are going to be changes due to the concussions and no one is going to care much for that athlete after they are off the field. Although i am not sure if it is possible to completely take concussions out of the game. The commissioners of professional leagues can still implement rules to help prevent them.
