Yes, Derek Armstrong, he of 200+ points over 470+ NHL games, was not an NHLer.That is like saying Derek Armstrong, Dylan McIlrath and Brad Smyth were NHL players cause they played some games in the NHL.

Come on, man. I understand your point, but at least in Libor Hajek's case there's a very good chance the guy sticks around long enough to play a couple hundred NHL games. That's exponentially more than most drafted players. He's an NHL player. Not a good one, but he is. Maybe he ends up going overseas after this year or something, but until that door shuts, he's an NHL player.
Gauthier I'm a little more iffy on, but he still spent the whole year on the NHL roster and still has a chance to stick on the NHL roster this year. He was an NHL player last year in some capacity and could be again this year.
