How is a player's position eligibility determined?
POSITION ELIGIBILITY
Before each season begins ESPN will determine the primary position of every NHL player available in the game. The criteria will primarily be the past year's playing time. This includes rookies as well as veterans. The listed primary positions are fixed and will not change for the duration of the season.

NOTE: In custom leagues the League Manager CANNOT change the listed position of any player in the game.

Rookies will be placed on the waiver wire / free agency either prior to the start of the season or after their first official game played.
