Let's take a look through recent history, through the hockey career of Bruno Idžan:
He started career when there were 2.5 ice rinks in Zagreb. Dom Sportova was primarily used as for EBEL/KHL and figure skating. A few croatian players can practice with EBEL/KHL team, but for most of them croatian leagues is only 16 games they play. Seasons of croatian leagues for youth levels are often started few months before respective World Cups, or sometimes even crazier, during the summer with 4 games or something.
Only positive thing was that one EBYSL season when Team Zagreb (behind name of Medvescak) played well. Every participation in regional competitons was filled with teams giving up games because they could not gather enough players or they didn't have any ice for weeks due to figure skating competitions or ice resurfacer being broken. Hockey in Croatia exists basically to squeeze money out of daddies watching Medvescak, but when it slowly stops being kids entertainment, teams didn't have urge to invest anything.
Idžan by the end of 2010s moves to Slovenia and that's where he saved his career.
What do you think Medvescak will do when this blackout of croatian hockey happens? Simply convert the new hall into a parking lot 1 year after construction? Even in the darkest hours of early 2020s, a dimmed light was still on on Džebolend and if the hockey survived then, it will survive now and if it won't, well, it's not like there ever was much of it anyway.
Now there is an ice hall for a hockey team, every age group has championships and international competitions are played with 3 lines or more. IIHF divisions? They come and go, who cares. Thing is hockey is growing in right now in better state than before. Having cynical opinion is one thing, but saying how croatian news outlets report that sisak bankrupted is a mean straight up lie. Not a single mention of it in more than 48 hours.
Idžan, a young man, product of this croatian hockey that went through all pains is now a PPG player in f*in USHL and was a topscorer in AlpsHL with 18! And you as a croatian fan decide to spend your days thinking how he'll most certainly fall off. Whatever...
To quote Team America at the end:
See, there are three kinds of people: d*s, p*s, and a*s. And all the a*s want is to shit all over everything.
