I "love" that Unsustainability-argument too. I agree fully with statistics, but I do not agree what they are allegedly supposed to mean. I expect Laine's long term Sh% will go downwards in longer run, but I do not draw that assumption from the statistics.
People who use stats as an argument, use them generally speaking "upside down", particularly so if they are stats that are derived not only from a player's performances, but also what happens around him, regardless of him. That sucks. Fault is not in the stats per se, it's primarily how they are interpreted. Laine's case is good example for that as argument for "luck" here looks simply ridiculous. (including that own goal)
I'm pessimist but I must agree with (very optimistic) Psycho_Dad that in the extreme case of individual the one must first check premises of the stats before straightforward application of their results to the practice.
How long odds have to be defied on the ice before adequate corrections to a formula of a stats will happen? (error is in the stats, not in the play on ice if a statistical anomaly cannot be otherwise explained)
In other words, stats guys claim that only 20% of hockey cannot be adequately put to formulas. What happens when an individual plays within that 20%? Was - for example - Lemieux, Hull (both), Gretzky, Orr... within the realm of perfect jurisdiction and subjugation of hockey stats when they played?
To defy odds... rather many hockey legends of the hockey history managed to do so in the past, few are doing so currently. Why Laine's case would be categorically different? Why any individual hockey player's case would be different?
Statistical analysis can set only some kind of limits for what can be reasonably expected to be happen on the ice, not for what can happen on the ice.
