Lots of room for rational disagreement about ASP. His stature and stride hurt him a little and don't think he'll grow much more than what he is now. But, he seems to have big smarts and lots of good ideas about how goals can be scored, including the really good idea of unleashing bombs and getting shots on net. Plus, he seems to give a shit about defense even if he has to improve a little. There's a level of "want-to" in his game that suggests he'll be able to adapt to NA style games and continue to improve.
I try to set expectations low. For me, I see a more mobile Marek Zidlicky as a pretty safe expectation. If, like Zidlicky, he turns out to be the highest scoring defenseman from his Draft class, that would be pretty cool.
