Such a catch-22 situation because if Tinner doesn't make the hit, he goes back to the bench and gets blasted for it. If he does make the hit, well... we all saw the results.
I didn't like that penalty one bit. It sends the wrong message entirely; the NHL is looking to get rid of dirty hits, not hits like this. The result was unfortunate (you never want to see a player get hurt) but if the guy pops right back up, there's no penalty on the play IMO. I think we're starting to head down a slippery slope where open-ice body contact is eliminated entirely, which would be terrible.
The NHL is caught in a bind, not only do they want to get rid of dirty and illegal hits, but they also want to reduce injuries as well, that is also high on their agenda.
They also really can't determine the penalty as a result of damage done (if a player pops up there is no penalty) since it creates double standards. A light tap could create injury whereas a blast may cause none. All would be under a referees personal judgement versus a hard rule, and would be very confusing for the players. After the fact just does not work to make things safer. Since the future and the results of a hit are not known beforehand,
all hits that could cause injury have to be eliminated beforehand to stop
any from occurring.
Reducing injuries is something that is happening with all sports and the NHL is just following suit. The NFL for example has outlawed many type hits that were legal but are no more. The NBA has added more responsibility to the player to stop the situation from occurring in the first place. FIFA has automatic cards for spikes to an opponents leg. All whether intentional or not.
Changes have already started in the lower levels in hockey and I think more will come with the NHL. A lot of what is legal now, may not be in the future. As an example, maybe only shoulder to shoulder hits will be legal. It is a difficult problem for NHL since they have to find that balance of making it safer to play but not change and ruin the game as we know it.
