Saints head coach Kellen Moore introductory press conference, media updates, February 13, 2025

He agreed to wave it for Oakland. I think approaching him on the paycut is option A. I agree there’s no incentive for him to do it but maybe Moore can coax him into wanting to be part of the offense. Option B is the trade route, it’s still better than an outright cut only in that both outcomes you pay him to be on another team but w/ trade you can atleast get an asset to help the team. Finally option C is to downright cut him
He actually didn't. He, or rather his agent, knew that it would be more lucrative for him to force the Raiders to cut him and not keep his old contract with less guarantees than a new one would get him.

The Raiders made the right decision. Hopefully the Saints will too.
