I do think you will see some movement, teams will have to do a better job of trading with each other to bail each other out instead of going through the expansion team. The last time around they literally gave the house all of the assets and created an instnt contender. Think Vegas sold off more than they should in terms of draft capital, but they are still solid. So Seattle should have more of an uphill battle.
As far as the Rangers go, to me there is an open forward slot for protection purposes. Does a guy grab it and earn it internally? Is there a trade for a youngish player that can support the new core from another team that can be an option? Time will tell.
But this go around, I think teams, especially those out west, would be better off giving a team in the east picks to take a guy instead of another team that can use it against you 4 straight years to grab a division title or a playoff spot while being a cup contender.
