I watched Salavat actually. Like come on, Chemelevski is a good player and in last season Hartikainen was either uninspired or was saving the best for playoffs, but Chemelevski is not on prime Harti, or Granlund level. I would even put Manninen ahead of him for now.
The issue is there is no such thing as "prime Harti" in this context, the league level every season consists of every player's actual performance, not the prime level of how good they were at some point, so I'm now talking about that Chmelevski v2023 was looking better than Harti v2022 and therefore in this particular case the replacement was more than effective.
Barach is just worse than Aaltonen, Ojamaki or Audette. Johnson and Dea are just worse than Maillet or Kovar for example. I can go on and you know it)
I know that you like to make conclusions after a dozen of games, but it is just dumb, as the same Chmelevski was looking rather meh the first like 20 games in, but somehow you're refusing to look into full last season like it wouldn't exist even though it is a much fuller data set. Not to mention that Kovar is a rather funny example, as as soon as his chemistry with Mozyakin and Zaripov stopped he was looking fine, but not like anything special.
However you brought up the Vityaz foreighners and it is a very solid example to compare, as they indeed were really good. So Vityaz had Aaltonen, Ojamaki, Audette and Kemilainen as foreigners in 2021/22 and had Wilson, Roy and Graovac in 2022/23. So the question here is if (considering the league foreigner numbers going down by about 40%) we can say that Wilson, Roy and Graovac would equal to about 60% of Aaltonen, Ojamaki, Audette and Kemilainen? If yes, than the quality wise it would be a proper replacement, not quantity wise, of course (hence the 60% coefficient).
Anyway, you are correct about 5 man import limit, which is why I think that KHL never established itself as a clear 2nd best league in the World and was always just a best of the rest, leader of that 2nd tier pack with SHL, AHL and NL even in its glorious days around 10 years ago. And thats why the money argument was never a decisive one aswell, I mean, KHL certainly has more money than anyone in Europe, but what does this money do? Sure they attract some expensive mercenaries, but main effect is that they overheat the internal market. As a result SKA and Avangard throw insane money at a mediocre russian player, We can all be happy for let's say Tolchinsky and his family, but his market value in Russia is like 4-5 times higher than in the outside World.
It is like a price of vodka in Iraq. Just the fact that it costs five times more doesn't mean it is any better than vodka in Finland.
I'm not arguing about the inefficient use of money, but money is still money and if SHL pays like 4 times less (considering taxes) it kind of is an important factor for foreign players.
