Hägg for Kapanen?
Done and done.
Morin or Myers for Kapanen?
No thankyou.
And I like Kasperi and have done since way before he was even drafted. His dad was one of my favourite players ever and I think he can develop into a good 2nd line NHL winger.
But Morin & Myers if they develop well will be top 4 NHL defenders with pretty rare skill-sets. Not often you get 6'8 & 6'5 guys who move so well with the skills they have. Guys like that are far harder to find than guys like Kapanen.
Also does not help that the Flyers already have: Konecny, Lindblom, Aube-Kubel, Laberge & Allison... who can all play RW and all have at ~2nd line or better upside. (though ofc different chances of achieving that upside.)
With Voracek, Simmonds & Schenn who are on the team right now as guys who can play RW to 1st line level already.
