Really? I see lot of potential, physical two-way winger with good shot. He's scoring ain't that bad considering this is is his 1st full pro year. He is 10th highest scoring U20 player in Allsvenskan, him and Noel Nordh are only 18-year olds in the top-10. Nordh has scored 3 points more in 6 more games and Nordh plays in highest scoring team in the league. Nygård's team Mora is 8th highest scoring team in the league.
Filip Forsberg scored 17 points in 43 games in 2011-12, previous year Forsberg played 10 games and scored 1 goal. Last season Nygård played 11 games and scored 3 points. In the J20 league 2010-11 season Forsberg scored 40 points in 36 games and last season in J20 Nygård scored 38 points in 35 games. Nygård is little behind of Forsberg in Allsvenskan scoring but ahead of him in J20 scoring. Forsberg turned out ok, despite his draft year scoring wasn't that high.
In the U20 Worlds Norway scored 8 goals, MBN had 5 points and +/- 0. Quite good considering Norway allowed most goals in the tournament. Easily a top-15 pick.
Greentree in the other hand is a man in boys league, that could make him look better than he is actually is. Dal Colle, Nick Ritchie, Virtanen, Brendan Perlini, Brett Connolly, Logan Brown, Cody Glass just to name few.
