To those who say "the cap can be cooked" -- it can, but not to an unlimited extent. The restructuring they are currently doing will cost them next year. Rodgers -- if he's back -- has a $59M bonus. If he retires after next season he has a Post-June 1 22.7M cap hit in 2024 and a 45.4M cap in 2025. That's on top of the restructured money you just kicked to 2024. What happens when you've kicked out 40-50M of money taking up 20% of your 2024 salary cap? What happens if you kick it further out, piling on top of the 45M Rodgers would count?

Cook away, sooner or later you won't be able to field a team (see: Bears).

If you only look at the team for 2023, they are better off at QB with Rodgers. If you look at the team over the next 3 years they are better off without him and giving Love a shot.
If he sucks you don't have to exercise his 5th year option and are likely drafting Caleb Williams or Drake May (both better prospects IMO than Jordan Love).
If he doesn't suck you have your next QB and can use the 5th year option to buy time to hammer out an extension. Either way, if Rodgers is gone you'd have the cap space to do it. You don't right now.
