I guess my question then is, why did the NHL ever change from 2005/06/07?
The hockey was fine then.
i actually agree with you here. Fans of other sports always comment about how much grey area there is in hockey officiating compared to other sports. You grab a football players cage, it get's called 99% of the time. You rough a QB after the pass, its called 99% of the time. The ball either hits the line or doesn't in tennis.
But a sport like hockey(and lacrosse) where you have many guys on the ice who are allowed to make physical contact with each other, and are all carrying big long sticks. Contact is going to happen all the time. That's why we can't have as many black and white calls in hockey. A stick will accidentally graze an opponent very often. By the rules, its slashing. That's why the ref has to now decide if the slash was hard enough to warrant a penalty.(grey area). Throw in the fact every ref will have a different opinion of what's hard enough and you get the inconsistency we have.
Essentially, I think the reasons are
A) The hockey world wouldn't support 20-30 penalties a game being called for 2-3 years until the culture changed and we could get back to 5-10 penalties a game(which is still probably too much for a lot of people)
b) it's too hard to watch 10 guys out there with 25 slashes,15 hooks, 10 cross checks per minute and at this speed, while trying to decide which ones are worth calling...and remain consistent in the eyes of thousands of different people.
Edit: Where i think the biggest issue is is game management. A ref will call something at one point, but not the exact same thing at another point if the score is a certain way. Or how they put away a whistle at the end of a game or in OT. Or makeup calls.
Basically i understand refs will miss stuff, and i understand every ref is different. I also understand the refs have to make judgements because it isn't black and white. I just wish refs were consistent in their own approach from game 1 of the season to game 15 of the playoffs, minute 1 of the game to minute 64 of the game in OT.
