2024 must be quite the legendary draft, if there's already 10 players better than a 16-year old defenceman holding his own at the same team as last years 1st overall pick.
Statwatchers think he's suddenly bad now because didn't make the WJC team due to questionable coaching decisions, or because he isn't PPG+ in the U20's or scoring in Liiga. Yet in reality he's keeping up good progression from last year, even though he's been out a lot due to sickness, injury, and international tournaments. He's still only played a handful of games in Liiga, in a role that he's never had before (3rd pair defenseman without powerplay minutes, with more defensive zone faceoffs than offensive zone) but he's still managing it just fine. We have to remember that this is still tough professional hockey, a league that doesn't regularly see any 16-year old players, let alone any16-year old defencemen who don't have a particularly strong physique to support them.
All he has to do for now is to just stay healthy, and get some good practice and experience from Liiga and earn the trust of his coach so that he can get some powerplay minutes in, and become more confident with his abilities. I don't care how good you look at 15, 16, or even 18, but how do you look at 25? That's where the smarts and skills come in.
He still has a mountain to climb to even make it to the NHL in the first place, but when someone is that smart and talented at such a young age, I wouldn't bet against them. Fortunately much like another former TPS prospect from a few years back, we're also talking about an exceptionally mature young man in Kiviharju, who too will likely be wearing a letter on his jersey early on in his professional career.
