Not to be a downer but I don't really see why he would be one to watch. His production in his league was mediocre at best. He wasn't invited to any national team tryouts. There's nothing about him that would at this point indicate him being an NHL prospect at all. I literally cannot think of any significant draft prospect who would have performed this poorly at such an age.
A comparison to the player who's currently considered the top 2003-born prospect for the 2021 draft:
Oliver Salo(u15 AAA league)
11g 8a 19p 15gp
Niko Huuhtanen(u16 AAA league):
23g 37a 60p in 22gp
