No. You can't improve having 10 ice rinks. Poland has less ice rinks than my New Jersey. I have been watching them since late 80's. During communism countries showed off on international stage through sports. Back then money was going to hockey from government. Once Poland became a commercialized country in 1989 every team sport went to shit. Only single athletes are great that train somewhere in huts, or excersise cheap sports.
Back then sport was not on this level that you see right now. Right now kids on YouTube have more hockey talent then all hockey players in 80's and 90's. It was much easier to compete. Not to mention back then it was best of 8, now it's best of 16. Poland will never ever crack top 8. It's a lost sport in Poland. They don't even have an idea how to build it. They would have to live in US or Canada for 20 years to actually understand it. Besides, they are not a Nordic country. Lost cause. Promotion to top 16 meaningless for hockey in Poland despite what all of them want you to believe.
They peaked in Calgary in 88.
A lot of the old sides in Warsaw disappeared and some older clubs. Attached to the military in some cases.
Of course ice hockey can be developed there. And away from it's traditional heartland in the very far south of Poland. It just needs as with other countries in the development stage more facilities and more access for kids. Then proceed to improve the standard of junior coaching and talent identification and send the best kids abroad. I understand where you're coming from but things can change.
Denmark are one of the best examples. For sure basketball, handball, association football and volleyball are the most popular team sports in Poland but that's not to say people there can't get behind hockey and improve with a logical long term plan. Following the development of rugby union in tier 2 and 3 nations even Poland Rugby have a better idea of how to develop the sport and juniors than their ice hockey counterparts.
The organization itself needs a thorough shake up and understanding of what it needs to do as the guardians of the sport in Poland. Unlike some sports though improvement in standards in ice hockey takes slightly longer.
