"Gustavsson is a classically trained Swedish goalie who has the components to be a franchise goaltender, but saw some dips in confidence during the year. His season boils down to excellent play everywhere else except in his primary league (J20). After Team Sweden barely beat Team Latvia and lost to Team USA, his addition to the lineup at the WJC U18 energized them to a 4 game win streak including a semifinal win over Team Canada. One of Gustavsson’s long standing trademarks has been his repeated save ability from close range in a laterally shot stuffing manner. He has a competitive blocker, and his stand up skating patterns are well developed." - Anthony Mauro, DraftBuzz Hockey
