There are some but I think mostly of them will play in AHL.
But Nashville has an really good forward contracted to next season. His name is Patric Hörnqvist. Currently he is playing the world championship for Sweden as had been one of the best goalscoring players throughout the tournament. He has a good scoring ability but needs really good passing-players beside him.
His teammates from Djurgården, Dick Axelsson, 21 years old and Daniel Larsson, 22 years old, will try their luck in north america aswell. Axelsson is a forward and has really good hands but lacks in toughness. He can score goals but sometimes he is completely invisible in games. You even wonder if he is playing. But I think he will appear in NHL the upcoming season. Guess what for which team he will play? Yes, thats right, Detroit. And I think that he would be really good in pair with Henrik Zetterberg.
Daniel Larsson is a goalie and will also go to Detroit. But he knows that he probably has to make one or two seasons in AHL before getting the chance in Detroit. He has played really good this season and is a modern butterfly-goalie that is very calm both on and off the ice. His weaknesses like all butterfly goalies is on pucks that are shot high. He didnt make the Swedish team for the world championship but was involved on the last training camp before the championship. For the moment I hardly doubt that he will be a 1st goalie in NHL the next 4-5 years but he will sure be a backup goalie.
Stefan Liv, goalie, that got the wrong shirtnumber in Detroit (he is very supusticios (sorry for my bad spelling)) and can only play in shirt no 1 will try to make another attempt in the NHL. His contract with Detroit ends at 1th july and he becames free agent and can get to another club, where he hopefully can have jersey 1.
There are some other players too but this is some of the players that will try their luck in the NHL. But it is better if you ask me if you wonder about any player.
