No Nate Walker
Who's Sergei Kocharov?
Per the WP:
For a player to get his name engraved on the trophy, he must have played in at least 41 regular season games or one game in the Stanley Cup finals, and while teams can petition for extras, all of the player names Washington has on the trophy meet that criteria. That means that while defenseman Jakub Jerabek and forwards Nathan Walker, Travis Boyd and Shane Gersich appeared in the postseason, their names aren’t on the Cup.
