The number of players the Packers had to let walk in Free Agency, as well as more cans being kicked forward just to hang on to a few, should tell you where things would have continued to head, if Rodgers remained. It was time to jump off the carousel.
My only point of contention with this--I don't think any free agent loses we've suffered were due to affordability. Part of roster churn is just letting guys go when their cap number doesn't match their valuation to the team.
I'm also of the opinion that tying up a big chunk of money in a quarterback isn't as big an issue as others do. I actually don't know what the practical maximum is (the theoretical maximum being where you can even sign 52 players to vet minimum contracts.) In the world according to me, your roster starts to rot off when you are either regularly drafting late (which having a good quarterback should cause) and/or whiffing on too many of your draft picks.
In 2020, we lost Martinez, Bulaga, Jimmy G, Fackrell, Spriggs...(I'm probably missing a few) but those names either weren't good or were getting up there.
In 2021, it was Linsley and Jamal Williams and a bunch of "meh" players. An argument could be made that Linsley allowed to leave due to cap reasons, but it was also his 3rd contract. In general, the Packers don't give linemen 3rd contracts (Bhak being a notable exception.)
In 2022, we lost Corey Bojorquez, Chandon Sullivan, MVS, ESB, Burks, Lucas Patrick. And we cut Z, but I blame his cut on the back injury and attitude more than anything else, though money did factor into the decision. Yes, Adams left in a trade situation, but by all reports, we offered him more money. His departure wasn't cap-driven
In 2023, we lost players at the end of their career or stop gap players. Amos is still up in the air, but that no one else has signed him leads me to believe the league doesn't view him as a priority or we've told him we plan to re-sign him once Rodgers is officially off the books.
If you disagree with the valuation of those players that we lost I'd like to hear what losses you think we experienced.
