Sven is a definite weapon defences would need to watch because he can create offence, but I simply don't think his game is NHL ready. It's best for him long term to stay where he is and really learn how to be a threat at a high level in the pros and his defensive game needs work to.
We just need to suck up the suck haha. I would like to see an offensive player called up though, like Granlund or even Hanowski/Knight.
Hanowski or Knight would be good. They're both older and have pretty low ceilings. Granlund I think should be eased in more, as Sven should have been.
