My non-informed guess is that Myers largely only wanted to go to Dallas, and the Wings negotiations / offer rumor were floated to drive the price up. Not saying the Wings didn't offer the 2nd, I think they did, but I don't think it was ever going to get truly accepted knowing Myers wouldn't waive.
I also wonder how much of the smoke with Vancouver is that too, their GM notoriously likes to use the media to try to up trade offers
