Karl Henriksson, currently injured, may or may not be qualified by the Rangers for next year but in two seasons he doesn't give much of an indication of being an NHL player. It looks like the Rangers missed on this 2019 low second round pick.
Corey Pronman had an interesting comment on the 2019 Swedish U18 team in an article reviewing the 2019 draft. Sweden won the U18 championship that season when it got hot during the championship round. Ten players from that team were drafted including Henriksson. One, Lucas Raymond, is a star. A second, Simon Holdstrom, an Islanders first round pick, seems to be a middle six player at best. But the eight other players up to this point have been disappointments.
There were 4 other first round picks from the U 18 team. Alexander Holtz was a #7 pick in the 2020 draft. He has been unable to secure a constant role for NJ and his name constantly comes up in trade talk involving NJ. But at least he is playing in the NHL. Philip Broberg, Edmonton's # 8 pick in the 2019 draft, spent most of this year in the AHL and it is unclear if he has a future in Edmonton. Victor Soderstrom, Phoenix's #11 pick in the 2019 draft, spent most of the year in the AHL and has not broken through with Phoenix/Utah. Tobias Bjornfot, LA's #22 pick, has moved this year from LA to Vegas and on to Florida.
There were four other players picked in the 2nd and 3rd rounds. In addition to Henriksson, there was Albert Johansson, Detroit's #60 pick, Albin Grewe, Detroit's #66 pick, and Hugo Alnefelt, Tampa's #71 pick. These four have played only 1 NHL game (Alnefolt back in 2021) with Grewe still playing in Sweden.
Pronman concluded that maybe the success of the 2018 Swedish team "artificially bumped up the perceived talent level of their players." The Rangers miss on Henriksson is not the only miss from players on that team.
