If anything, the NHL shot themselves in the foot. Once the league became much more fast paced, the hitting increased. It’s the speed of he game that is causing a lot of this hardcore collisions in the ice.
With this speed, It’s hard to try to be mindful, as well as being able to dictate where the player you are hitting will suddenly change their positioning. A lot of the times it just happens. Besides a majority of concussions don’t alwats happen with head contact, but solid AND legal body checks.
It’s part of the game, and a player like a Lindros should know that. He was an animal and made extremely questionable and dangerous hits on his opponents. He tried to hurt you. That only became a problem once he was exposed for the way he skated, and then he became the prey. I feel like back in the day, there was more responsibility for the player getting hit rather than the hitter. Not saying that is always the case, but when you skate with your head down, turn your back while on the boards, or accept/give suicide passes, I feel some fault should be on the player receiving the hit.
If you get rid of physicality in hockey, then football, boxing, MMA, even Wrestling will all suffer the same fate. These professional athletes know the risks, they know what they are getting themselves into, and no one forced them....but for some reason we are now giving every unfortunate athlete a pity party because they were somehow “unaware.” I’m not for anyone getting hurt, or anyone losing years off their life because of sports injuries, but in many ways....it’s part of risk/reward.
