I still think there is a sizable gap between Schenn and Kostins skill level. I don't see Kostin being the playmaker Schenn is. In limited time in the AHL in his D+2 and D+3 years, Schenn had 19 points in 14 games, Kostin has 32 in 80 games. Kostin was good in the WJC, Schenn broke records. Everything Kostin has done up to this point, Schenn had done more. Maybe Kostin's body is better suited for the NHL, but the super athletes don't always develop in hockey. You can improve your strength, improving your vision or hockey sense is not as easy.
I simply don't buy the scoring upside with Kostin until he, you know, starts scoring. I know he has always played in men's leagues and has been pushed down the lineup, etc. That's fine, but scoring doesn't get any easier in the NHL. Until then, I still have him pegged as a 3rd line production/skill kind of guy. His shot might be legit, but a lot of 3rd liners have a good shot and don't do a lot else.
