You’re getting it mixed up.
the required games has to do with Vancouver being required to expose players with that much experience.
capfriendly has a whole section on the expansion draft with listing which players are eligible to meet the requirements and which players are exempt
Not correct as in the rules it states that if a player has not played 40 games in the previous season and is a 1st or 2nd year player then the player is exempted from the expansion draft and Juolevi has only played 15 NHL games in his career making this season his first season.
“* All first- and second-year professionals, as well as all unsigned draft choices, will be exempt from selection (and will not be counted toward their club's applicable protection limits).
Player Exposure Requirements
* All Clubs must meet the following minimum requirements regarding players exposed for selection in the Expansion Draft:
i) One defenseman who is a) under contract in 2017-18 and b) played in 40 or more NHL games the prior season OR played in 70 or more NHL games in the prior two seasons.”
So by this definition Juolevi is exempt and he is only listed on all these sites mock expansion drafts because he was expected to be in the team and play the 40 games.
