Cody Ceci is actually quite a good player, and I enjoyed his work in Edmonton (esp. in the 2022-23 season, which was his best of the three by some distance).
The only issue with Ceci is that he is... slow. One thing Edmonton has done a good job of since last summer is shifting their D-core to become really fast, and fast at puck-moving. Guys like Stecher and Klingberg and Walman are all zippy, fast skaters who make a good first pass. Bouchard isn't exactly speedy out there, but damn he can make quick first passes as well as anybody in the League.
Ironically, it's only the Oilers' best overall Dman, Mattias Ekholm, who is kind of slow, and that's mainly because he's getting old. But he remains their best shut-down guy.
