The Arizona Coyotes are "rebuilding", or "getting younger," whatever you want to call it. Their playoff chances in the West next year are remote at best, and given the positive developments in Edmonton, they are probably the odds-on favorite to finish last in the conference.
They most likely do not have to tank to secure a high pick in next year's draft and have a shot at selecting Auston Matthews. So why not get a few more quality NHLers to improve next year's win total? They do not even have to bring in new blood but rather retain two solid contributors from the past few seasons: David Moss and Martin Erat.
