I have never understood this type of comparison except for the 'we drafted this player in this round and maybe it will happen again' theory.
from Helene St. James of the Detroit Free Press,
They are the long shots of the drafts, the players who, if they become regulars in the NHL, are referred to as "later-round gems."
Notable players drafted in rounds 4-7 by the Detroit Red Wings include Sergei Fedorov, Henrik Zetterberg, Pavel Datsyuk, Gustav Nyquist, Darren Helm and Petr Mrazek. In the 2020 NHL draft, general manager Steve Yzerman and his scouting staff mined the later rounds for two forwards, two defensemen and one goaltender in hopes of adding a player or two to the rebuild.
