The problem is that I don't think Purdy counts as finding your QB and $55 million AAV per year is a lot of money to pay for a guy that is not your QB. I think they won with him because his cheap contract allowed them to pay guys like Deebo and McCaffery. But, you can't really do those things if you are paying Purdy $55 million AAV.
And, if you are tearing the team apart and let Purdy go, they are likely to pick high next year so they can draft a young QB. I'd feel different if they were keeping there other players to go for it with Purdy, but that's not what they are doing.
