Watching the world junior hockey final, it became clear why the average Canadian hockey fan hates (and therefore underrates) Dominik Hasek. It is because the cardinal sin in Canadian hockey is diving.
Canadians hate diving so much that they often see it even when it doesn't exist. Go down lightly once or twice, and every single time thereafter will be seen as a dive. Whenever Swedish goalie Jacob Markstrom was run in the final the fans thought it was a dive, and they got on Markstrom's case, booing him when he touched the puck and even when he was called up to accept the best goalie of the tournament award. Apparently the general consensus is that when you come out of your net to play the puck, and get hit during your follow-through with most of your weight on your lead foot, and that same plant foot is taken out by one of the fastest skaters on the ice plowing into you at top speed, knocking your stick out of your hands and spinning you around so fast that your helmet flies off and nearly clears the zone -- it must have been a dive. Bloggers everywhere are trying to outdo each other in hyperbole - according to one, it was "the worst dive in the history of sport." Give me a break.
I'm not saying Markstrom was completely innocent by any means, but I don't see how he had any chance of winning either of those collisions with Esposito or Della Rovere. How much he embellished is I guess a matter of opinion. I say not really that much on all except one of them, but you can judge for yourself from the Youtube clip.
Dominik Hasek usually left no doubt about his unsporting manipulation of referees. He knew exactly what he was doing when he was drawing contact or feigning injury, not to mention things like complaining to the referees and knocking the net off its moorings when the opposing team was just about to score. Those type of antics just do not mesh with the Canadian hockey worldview, and as a result Hasek pays the price in the court of public opinion. Take a look at this comment thread if you want to see what the average Canadian hockey fan thinks about Dominik Hasek. I recommend you don't, as it is basically a bunch of things like: "Hasek is the best at whining like a little girl" and "He is a diver and embellisher which could make him one of the all time greats if he played soccer" and "Domenik the quitter, you have got to be kidding me. He wouldn't even make it onto my top 15 all time list."
I think that sentiment is generally correct (i.e. Hasek had a greater-than-usual predisposition towards diving, embellishing, whining and possibly even quitting), but at the end of the day you have to evaluate the whole package, and for Hasek that includes his dominating puck-stopping abilities. It would have been better if Hasek did not do those things, but he grew up in an Eastern European country where they don't have a similar stigma against diving and he was also a bit of a jerk, that's just who he was. It is easy to exaggerate the negative tendencies, but diving (while regrettable and unsportsmanlike) really has little negative cost in terms of winning or losing games. It is really more of a style issue, and at the end of the day, performance is far more important than style for ranking hockey players.
