I don't think it's that. Neely essentially admitted that they were all high on bath salts when they put that list together. I'm kidding, obviously, but in 2021 he said that he knows they royally screwed up that first round and that he thought about that draft a lot. He said they didn't take a timeout and digest the list before they hit the draft floor. It sounds like they weren't prepared, which is on Sweeney, Gretzky, and Malkoc.
Sweeney said that whole draft weekend was a steep learning curve, which I took to mean that they did a terrible job of preparing for the draft and he didn't really question the scouts as to why they were probably the only team in the league that had DeBrusk and Senyshyn above Barzal and Connor on their draft list.
I do think Sweeney has an attachment to Jake, though. Friedman mentioned a few years ago that Brad Treliving was reluctant to move Sam Bennett for a few years because Bennett was his first draft pick as GM and he had an attachment to the player. Granted, Jake wasn't Sweeney's first draft pick as GM, but he was in his first draft. Sweeney has bent over backwards to keep Jake on the roster and happy, whether it was not exposing him to Seattle, not trading him when his stock was higher, and firing Cassidy because Jake (and other players) didn't like him.
