That is not what this says. That is good if what you have is true.
The Curious Role Of UFAs In The Expansion Draft - SinBin.vegas
I don't see anything in there saying they have to protect someone with a NMC that is expiring, just that a team has the option to protect someone on an expiring contract. The other articles were also posted later on, so I believe them to be closer to reality as they'd have the benefit of further clarification of the rules by the league and team executives.
* All players who have currently effective and continuing "No Movement" clauses at the time of the Expansion Draft (and who to decline to waive such clauses) must be protected (and will be counted toward their club's applicable protection limits).
Expansion Draft: Full Rules
I think the key word on the official rules posted on the NHL site is "continuing". Continuing must have been clarified to mean continuing into the next season at some point. Whereas "effective" is in the wording to ensure that players with NMCs that are not yet valid wouldn't need protection.
I just can't find anything official. I think Dennis Wideman last time was an example like Russell where he didn't need to be protected despite having an NMC as it was expiring prior to the next contract year.
At the end of the day, even if the rule was so stupid to make teams protect expiring NMCs, most players wouldn't force the matter anyways as they know their chances of being picked as a UFA are non-existent. Particularly as the rules also require that the drafting team selects at least 20 players that are under contract meaning at most 9 selected players could not have contracts the following year.
They aren't going to burn one of those spots for bottom pairing UFA dman, they are saving those for quality RFAs that may go unprotected as there's likely a goldmine of players on their first expiring contract that you could go after here that could be close to emerging. Knowing this, a player would only enforce it to be a jerk to his team as he'd have no reason to actually even talk to Seattle if he didn't want to. I don't get the impression Russell would do that.
