For people not understanding the trade:
Arizona shed some cash, and got back a young-ish player in Mackey. They also got worse, helping to increase their Bedard odds.
Calgary got better unquestionably as Zadorov-Stecher should be a reliable 3rd pairing now. Nick is also an upgrade on Brett in goal scoring, but a downgrade in other areas as Brett was always hustling and forechecking. Flames have very strong underlying metrics, but have not had steady goaltending, and perhaps a few too many grade-A chances against at times compounding this issue. Treliving didn't want to give up on this team yet, but didn't spend any futures on this group either. He stated that he did listen on offers for some players under contract for next season, but that those offers were not strong enough.
Brett recently has been displaced in the lineup from Walker Duehr who has looked good. Treliving stated in the presser that this helped to give Duehr more time on the roster, and allowed Brett to still play. Curious as to who Treliving feels will be displaced by Nick Ritchie now.
I do think that this makes Calgary better. I am just not sure how much. I don't think it is enough to catch anyone. I bet Nashville still passes Calgary too. Personally, it wasn't the trade-deadline that I wanted to see from the Flames, but it is better than being a buyer given their circumstances.
Whomever you want to point fingers at, and whatever your theories are, everyone can at least agree that this season has been underwhelming in so many areas, with only a few bright spots.
I will personally miss Brett Ritchie on the team, as when he is in the lineup I don't think there is ever a moment that I felt he didn't give it a good effort. He is a solid forechecker who doesn't stop skating, and he won't hesitate to drop the mitts and stand up for a teammate either. Solid 4th liner.
