Yeah some of those should be kicked for a while meanwhile they can build a strong KHL competitive team and return later.
200K population cities have also suburbs you know, Nizhnekamsk has not even 240K and still plays in KHL so demographics is not the case here.
Why it should not be established there can you tell me ?
Are you serious or trolling? How can Kuzyna or Severstal be more
competitive while paying in VHL? They would just cease to exist in one or two years. Those teams are already in KHL. Downgrading them to "improve" is your idea? So, playing against Neva would promise more improvement for Kuzyna rather than SKA? Or going to Krasnoyarsk for a hockey game is much more logical than playing Sibir away? Is this your mindset to develop those teams?
As for the second part, so you say 200K population cities have suburbs but you do not like Nijnekamsk with 240K people which already has an established ice hockey team, playing in KHL for years? I think you should get some good sleep, have a nice breakfast, store energy and come back later to write here.
I can understand if someone says a few teams should be dropped to VHL to make the league more competitive but when you include Minsk, Amur, Traktor in this list and then later say Volgograd, Sakhalin should be added... It just becomes pure nonsense, sorry.
By the way, population is not that important, especially for Eurasian ice hockey where the biggest arenas can hold around 12-15K people. It's not like football where you need bigger crowds to be relevant. I can name you many successful sports organizations based in relatively small cities. Take Villarreal CF, for example. Among the best teams in Spain. Definitely a competitive La Liga team which also plays in European competitions. From Villarreal, a place which has a population of 50K. And this is for football. Let's take a look at hockey: I admit Luleå is not the best team in Sweden but they are very competitive and surely would do good in KHL. Population? 75K. HC Davos, the most successful team in the Swiss history, is based in a town of 10K people. The most recent Extraliga champions, Verva Litvinov, are from Litvinov which is a town with almost 30K people.
So, as long as people are interested in ice hockey, even 20K or 30K would do the job for a team. Moreover, ticket prices are not an important item for KHL. I am sure it doesn't much for Sibir if they sell out or just remain at 5K. More fans make the league better, maybe put some pressure on opponents and that's it. In this sense, hating on Nijnekamsk and asking for a team in Volgograd or Sahalin, especially if you think that Amur and Traktor should be taken out (still can't believe you said that) is... Well, let's say, weird. Sure, you would expect KHL to put emphasize on bigger and more populous regions for marketing purposes, but again, asking Traktor or Amur to leave contradicts with this concept.
