This was without question the right move (and probably a year late at a minimum). You need to keep things fresh for players when they go through extended periods of losing.
That said, those who are expecting a materially different product from the Wings next year will be disappointed unless we see material improvements to the roster (especially the blueline). If you are running a comparative fault analysis of this team, our overall talent level is most responsible for our current placement in the standings. It really isn't even close. Over the long term, teams will also play to their collective talent levels. It does not matter the level of hockey. Over time coaching will become more important as it becomes more difficult to improve upon talent. We are still a long ways from that. I think our next hire will also be a bit of a placeholder of sorts for a couple of years.
Anyways, I applaud the move even if we are up against several other clubs in the coaching market this summer. A new voice is very much needed.
