As a friend of Teuvo, I can tell you he couldn't be happier to be a BlackHawk. Before the draft he told me his favorite player was Patrick Kane and he idolizes him. Learning from Kane is something he's very excited for.
He also told me a couple months ago he wants to play the point on the PP. Just thought I'd let BlackHawk fans know that
EDIT: Just looking at some real old text messages before the draft he told me where he wanted to be drafted...this is what he said:
"wish list: flyers,chicago,anaheim,tampa,montreal,carolina,ottawa,
maybe anaheim is number one"
He explained the Ducks because of the Finnish connection, his top 3 favorite teams before the draft were the Flyers, Ducks and BlackHawks. He wasn't a huge fan of NHL though, a lot of the explanation for his favorite teams can be rooted from their Finnish player connections and him learning about the teams closer to the draft when he met with their personnel.
