Spoken like a person that has never played a game of rugby league.
I played in an era where the game was a lot harder then the present day - you actually pushed in scrums, 4 replacement rule, all in brawls, head high tackles, knees, someone trying to denut you in a tackle etc etc. Shoulder charges were not part of the game - so when you see a player have his head jolted severely from a shoulder charge you know that the player will have problems later in life; especially if they are blinded sided.
As I said, it might be good for the lounge chair critic but it is not good for the person on the receiving end.
There will always be accidential injuries in all sports, such as, the player's recent death in hockey, and there will be future accidents in RL, it just doesn't need to be deliberate when you know it will lead to health issues in later life.
I played the game for 25 years and have major knee and ankle problems - no problems that is part of participating in a hard sport. I now have two sons playing at a fairly high level, my greatest fear - them being blindside by a shoulder charge not a punch in the nose, raking across the face. etc
The players are real people, they are not figures in a Xbox game. To see someone with brain damage from numeruos sub-concussions is not a pretty sight.
