Is it ideal for 2025? No, however they still have to play the games. Anything can happen. It makes the 2026 decision easier based on how he plays - if he does well, play out the string, and if it’s bad then the team can afford the out a little easier and address QB in what should be a much stronger draft class for QBs than this one.
That's how I see it too. The Saints will or won't do well this year with Carr at QB. The Saints understand that it could go either way, so they set themselves up to go either way depending on how things turn out this year.
I think giving yourself the most flexibility to respond to unpredictable events and outcomes is always the best way to go.
