I guess we could always argue about how many underagers we should put into our national team, but Gästrin and Härenstam seems like bad choices to me if you are going to pick additional players. Härenstam because he has barely played this season, and while I fully admit I have watched less games this season, and both of these guys have "pedigree" in terms of being better players earlier(which shouldn't mean anything now anyways). But I can't say that Gästrin has even been significantly better than Nilsson or Hillström in the games I've seen this season. Frondell has to rip the j20 apart to get a shot at the u18 team, but Gästrin is middle of the pack amongst the nationals in his own age group and gets in? Especially considering that I dont' even think he has taken particularly big steps as a player anyways. Maybe he has been fantastic post new year and I just haven't seen those games, but seems like the classic "national staff falls in love with a center and plays him any chance they get", a la Forsfjäll or Wille Johansson.
Will be interesting to see how Frondell and Annborn continues to do, and I do think the u17 team looks really fun overall. Probably a lower end player in this team, but cool that Vass gets a shot as well.
