The Oilers made many detrimental moves this summer. They gave up assets for Duncan Keith without any salary retention, they didn't upgrade either goaltender in their tandem, and they watched the 2020 Leafs and decided to replicate their defence by re-signing
Tyson Barrie and giving
Cody Ceci a 4-year contract that pays him $3.2 million per season. They brought in
Zach Hyman, which has yielded mixed results, but ultimately, they used the cap space they had on moves that won't fix the Oilers problems. That's on the GM.
