So much bullshit in this thread. Kasper has the skillet to become at least a solid second line center on any team. He may not become the next Crosby but he will be a player who is though to play against.
If you judge him by his numbers in a pro-league VS men at the age of 17 then you have to rethink about your scouting methods.
When Kasper was younger (14,15) he was more a playmaking center. In Rögle they asked him to be more aggressive around the net, so he did. They also asked him to go to the rough areas, so he also did. Kasper will do what the coach asks for and he quickly adapts to any style of play. That's maybe one of his strengths nobody has pointed out so far.
I also do think that Kasper is very close to make detroits roster. Just keep in mind that he has been playing in a men's league at the age of 17. Because of the Fa-signings another year in Rögle/AHL (playing against Pro's in a top-6 role) won't hurt his developement for sure, but out of this draft class he may be the most NHL-ready prospect.
