Tough call really between Niku and Vesa.
Niku unquestionably excelled in North America in his first season here. But that's at the AHL level, not the NHL level. His tiny NHL sample size doesn't count for much with me, even though he looked quite good. Defencemen traditionally take longer to get all aspects of the NHL game and while I couldn't agree more that Niku's ceiling is very high I'm in no hurry to have him on the Jets. I want the Morrissey approach with him (and frankly all NHL D draft picks we have) - let them season in the A for a couple of years. If he knocks down the door in training camp, well, throw that out but if he's just meh then another year won't kill us.
Vesa had an exceptional season in a men's league, on par with some substantially higher draft picks that play in the same league over time. He has numerous tools, skill and size. Duly noting his shooting percentage. But he accomplished quite a lot on a team that wasn't stellar, emerging in some aspects as a leader at a very young age. The NHL is generally kinder and easier to break into for wingers and I think Vesa is able to stick with the team this year. I won't be heartbroken if he plays a year in the A to learn the North American game a little better but I think he has better odds of sticking with the team this year so went with him.
Pretty hard not to be excited with a pair of guys that might forecast out as Karlsson-lite and Wheeler-esque (ceiling of course, not expectation).
