Kupari has more experience in the Liga since he is currently playing his 2nd full season in that league... Tons of factors may explain why a kid is producing more than another at a very young age in the Liga, every teams are different, have different setups and bring their kids at different paces... Thing is, most of us dont know much about the Liga since their games are hardly watchable, we dont know how Kupari is being used in comparison to Ylonen, does he has better linemates? Does he play on the top 6? Does he get first PP unit minutes? Apparently Ylonen is playing on a third line and on the 2nd PP unit, thats all what we know, we dont know if the first PP wave eats basically the whole 2 minutes or if the setup is similar to the Habs for example where both units are sharing about 1 min each...
But since you apparently watched alot of Ylonen, Im expecting you to elaborate furthermore about his use and all (dont forget to give us your secret infos so we can share FEL games as well), as far as Im concerned, I only had the WJC to scrutinize his game and believe me I did my homework, you can see my scouting report on Ylonen on the link below...
Not only Ylonen carried a third line by his own offensively, but he easily outplayed and outscored guys like Tolvainen (top ranked prospect) and Kupari (who showed great speed but nutshell hockey IQ through this tournamen), all that despite 2nd PP use while the top line got all the opportunities in the world to shine and made very little use of that... Swap Ylonen and Tolvainen (who scored 1 goal in the whole tournament) and you probably have a total different view of Ylonen who highly probably ends up as the best scorer of the tournament...
