The "rise" and "fall" of some of these players is completely media driven. I highly doubt it's as much of a thing inside NHL organizations.
Most of these players haven't played a single game in 6 months, so not a whole lot has changed. Sure, some of the European players can alter their stock slightly, since they're actually playing again, but even then, I doubt a team that has heavily scouted a Stutzle or Raymond are seeing anything they didn't already know about the player.
The meetings / interviews since March could change things slightly as well, but again, teams (general managers / scouts) have gotten to know these kids inside and out long before the stoppage.
I would think if Sanderson were ranked 5th on a team's draft board back in March, he's still right around there in September / October.
