Liiga isn't as good as it used to be, even from the days Granlund was there. It is a league full of men, so it does have that going for it, and that's about it. I'm not really expecting a whole lot from Kiviharu next year given his age and coming off a season of injuries, but if he's going to stay in Liiga for more than a couple years I want to see him really start to dominate it by the end of the 2025-26 season.
Large ice plays a big factor for Kiviharju, too - in a good way. Sure, defending against men is still defending against men, but I'd like to see him play one full year in Liiga, then make the jump. I don't necessarily need him to dominate, I just want him as an established top-4 presence in a good team. To me, that'd be plenty in D+1.
Great thing here is that Aron can get small ice experience during training camps. No, it's not the real thing, but there's plenty of those around him willing to tell what he needs to do in order to not only make it but thrive in the NHL. He's undersized, but that also means a low centre of gravity, something Spurgeon has used to his advantage throughout his career in muscling off bigger guys. Yes, I see you balk there, usual suspects. He's done that well, especially along the boards.
As for Liiga? I'd say your assumption is correct. It should've gotten a boost from lots of Finnish players that returned from KHL (for obvious reasons), yet I just don't see that so far. The level is also brought down by the # of teams. Squeeze it down to 12 or so, make it open again - and not just with cabinet decisions. Bottom one relegated, top Mestis team promoted, next two go to playoffs with Mestis 2 & 3 for league spots. Unlikely to happen, but that's how I'd like to see it. Right now the best Liiga players tend to be bought by SHL (Sweden) or NL (Switzerland) teams, and while top Liiga rosters are still elite European teams, the league as a whole has taken a step down. However, that's beyond the scope of this thread and frankly, I'm not qualified to elaborate further on the why's or, in terms of fixing, how's - beyond my opinion regarding bloated # of teams at least.
