So it looks like we have 208 names who made the Round 1 aggregate list. There were 220 names on the "best player by position" projects (which were done from 2011 to 2015).
Here are the 28 players on our Round 1 list who weren't included in the "best player by position" projects:
George Armstrong, Dan Bain, Patrice Bergeron, Vsevolod Bobrov, Georges Boucher, Drew Doughty, Frank Foyston, Bob Gainey, Hap Holmes, Patrick Kane, Erik Karlsson, Duncan Keith, Anze Kopitar, Pat LaFontaine, Eddie Litzenberger, Hakan Loob, Connor McDavid, Frank McGee, Carey Price, Nikolai Sologubov, Steven Stamkos, Vyacheslav Starshinov, Jonathan Toews, Sven Tumba, Jack Walker, Shea Weber, Hayley Wickenheiser, Vladimir Zabrodsky
Of those, 11 are active players (Bergeron, Doughty, Kane, Karlsson, Keith, Kopitar, McDavid, Price, Stamkos, Toews, Weber) who have either started their careers, or significantly added to their legacies, since the lists were made. The remainder is an interesting mix of primarily Europeans, old-timers, and one woman.
