From HP.com's Black Bible:
"Joel Blomqvist is a technically refined goalie with some of the better skating mechanics featured in this draft. He has a very narrow stance, and understands how to make rapid micro-adjustments in order to correct for an angle that he initially failed to pick up on. His skating and stance allow him to move laterally at an excellent level, allowing him to make difficult one-timer saves. His adjustments, blend seamlessly into his fluidity between movements... His ability to make high-end saves off of lateral passes thanks to his side-to-side movement, and his ability to make recovery saves thanks to his ability to micro-adjust, give him the foundational base that you look for when breaking down the highest percentage of goals that go in, in the NHL.
Another area that we look for that’s extremely important is the glove hand and that’s another element of his game that shines. He keeps good positioning and is one of the best in this class at tracking shots labelled in the top corner on his glove side. His catching consistency was fantastic in our viewings. His tracking doesn’t just extend to his glove though. He’s excellent at remaining calm without throwing himself out of a play.
Blomqvist was also one of the better goalies we saw this season during breakaways. His poise and hockey sense help him form a net presence despite not being a very big netminder. His refined skill can be seen in his butterfly as well. He can transition in and out of the movement very quickly, and it was extremely rare to see him beat five hole due ton his stick positioning. His rebound control was a byproduct of how refined his movements are as well. He’s very good at staying compact so that he can fully extend rapidly. His reflexes compliment his skillset, and make it very difficult to beat him in high-danger areas directly in-front of him.
Goalies at his age need to improve everywhere but the areas that need the most improvement include his blocker side when he’s extending outward to his side, and how quickly he can rotate his glove down to take shots that are ankle level. This specific area was where he let in the most low danger goals in our viewings."
