Oilers have been getting screwed over on calls for years. I don't watch many other games in the NHL, so I couldn't really say if its across the board for all the other teams, but I know that the Oilers get screwed a lot. I would think, that the NHL would want to correct this, so that fans can expect, and get, properly officiated games.
However, it is not. Doesn't look like it will be for a long time either. Don't ever remember officiating being this bad before Bettman. However, it seems six rules change every offseason, so its to the point that no one knows what the rule is supposed to do, or how its to be implemented.
Point is, they love this controversy. Reminds me of wrestling. It seems the NHL feels that fans leaving angry, or upset is just fine. As long as they have an emotional investment in it, they will be back. So, to me, its sports entertainment, right down to the script. When the NHL tried expansion south in the seventies, it didn't work because the Canadian teams were to strong. That is why Atlanta came north. It has only worked with Bettman's years, because I believe that the refs do manage the games. What a penalty today is a far cry from what it used to be. All those penalties sure take flow from the game, and slow it down. Can't take it seriously anymore, just take it for what it is. Sports entertainment. If you don't like it that way, your watching the wrong league.
