There is a big difference between 1 year after the draft and about 7 years after a players draft. Obviously Weber is a better player than Phaneuf.
Granlund may be a better playmaker, but Nino is a sniper/powerforward. I would take Nino over Granlund because it will be much easier for Nino to break into the league with how big of a kid he is, and Granlund is about 5'8 ~165lbs, he's very small. I'm not saying Granlund won't make the NHL and be successful, but there is a much bigger risk for injuries and his play not translating well, compared to Nino.
Granlund is about 5'11 180-185lbs, You take Nino because you are islander fan
. Granlund have played with full grown mens for 2 years in 3rd most physical league in whole world behind NHL and AHL. Size has never been issue for him, he plays bigger than he is, works hard and has very high hockey IQ. The biggest problem for granlund to adjust into NA rink and game pace. Nino has to adjust game against adults, Granlund isn't risky pick at all, you haven't seen enough of Granlund. Granlund would be top 6 player this year if he wanted. How about Nino? Granlund has higher ceiling and Granlund is better overall player, and is more proven. There's no way that Nino is over Granlund. Not even close Granlund is better player at defense and offense. Size wasn't issue against NHLer's at the WC, NHL defenders/ex NHL defenders had huge problems to strip him off the puck without getting penalty. Granlund has won so much before even turning 20 being crucial player for his team. People seem to forget it. Mentally very strong kid, when the pressure is higher the better performance. I don't say who is better in the future because i can't tell how both developes but at this point Granlund is way better player, maybe it's hard to admit as a islander fan. You can't learn hockey sense much anymore at 19 but you can get stronger very easily. If granlund was soft then i would be worried but Granlund plays with high intensity and gives huge hits.
here's season 09-10 highlights of Granlund
