"A player will be considered a prospect until he meets the following criteria:
If a prospect is a skater (forward, defenseman) and has played in 65 NHL games or more before the completion of the season of his 24th birthday; or, if a goaltender has played in 45 NHL games before the completion of the season of his 24th birthday, that player will be considered graduated to the NHL. Conversely, if a player completes the season of his 24th birthday without passing those milestones, then that player will no longer be considered a prospect by Hockey’s Future, regardless of the player’s status with his NHL club."
Please re-read my post. I specifically said I'm no advocating trading Murray, nor would I, nor am I a GM, just simply pointing out how fallacious the previous poster's statement was.
