Par Lindholm. Apparently he turned down some NHL offer the past summer, and so most likely that offer was a 2-way deal. I could see him get a 1-way deal before next season.
Less obvious guys I want to see sign an NHL contract includes Dominik Kahun (Germany) and Michal Cajkovsky (Slovakia).
Kahun impressed me already at the world juniors playing next to Leon Draisaitl, and he's had a strong development in Germany since. Too bad he wasn't drafted. If some NHL team worked with him from an earlier age, I think he could have been a pretty good player by now.
Cajkovsky has the physical attributes for the NHL, and a bit of a meanstreak as well. Skates pretty well for man his size, can pass and shoot. The question is if he could withstand the tempo of the NHL.
Either way, I don't think either of them will recieve 1-way offers from NHL teams, and so they'll probably prefer to stay in Europe and make more money.
