My belated thoughts on Vesalainen:
1) I really like the pick. No one at #13 or #24 was a sure bet, including KV, but he had arguably the highest ceiling and a high floor, as well.
Ceiling= Blake Wheeler ; Floor=this coming season's Joel Armia, who I am pegging for 30 points, i.e., solid 2RW production
2)He is a very young prospect, and spent last season, as a 17 year old, in a foreign environment, obviously struggling emotionally with a variety of challenges. This is not predictive of anything long term and I get no sense of E Kane here at all. If anything, his more assertive personality will be an asset for him, in comparison to, e.g., Armia, whose shy nature was a detriment to him early on.
3)Since I've mentioned Armia twice, here are the differences. KV is significantly sturdier--an inch taller and ~20 lb heavier at the same age. He could easily round out at 6'5 and 230. He also seems to have a more assertive style on the ice, which, along side his speed and hands, gives him a lot of options in the NHL.
4)I can't comment on his hockey IQ, other than to say it appears he is developing a well rounded positional/posession game,and that puck distribution is less of an issue for wingers. (Laine was also criticized for this IIRC). I would not be surprised if his hockey sense limits him to some degree, but with a creative centre it may not be an issue.
I don't expect we will see Vesalainen in the lineup for 2-3 years. Only truly elite Finns have been able to make the jump at an early age....but I think he will be worth the wait.
