@GeeWally re Rask and waivers.
As you know, the last CBA has been extended and anything changed in it is covered by the Memorandum of Understanding.
Here's the only change to waivers:
CBA 13.23 amended such that it shall continue to apply to another Club’s RFA but it shall not apply to UFAs who play for a club outside North America after the start of the NHL Regular Season through and including December 15.
That changes what I said earlier in my response to you, that it only applies if he plays a game in Europe. That is this section of the CBA
13.23 In the event a professional or former professional Player plays in a league outside North America after the start of the NHL Regular Season, other than on Loan from his Club, he may thereafter play in the NHL during that Playing Season (including Playoffs) only if he has first either cleared or been obtained via Waivers.
So, to answer your question, I have no clue what KPD is talking about, who gave him that information, or if something else changed that I am oblivious to. (and you know me, I like to keep up on these things).
Hope that answers your question.
