I don't think they're going to invest too much in a back up for Love. He's going to sink or swim. Next year he'll either be entrenched in the job, or gone. Nobody knows, not even Love himself. There will probably be a UDFA on the practice squad at QB, and the back up himself will be someone who understands the system being used, but is at best, a journeyman. As for myself? I don't care, because I have no high expectations, and realize that the worse they do the higher their picks in 2024. That would at least soften some of the blow, if Love blows the chance he's getting.
Personally, I think Love will be a respectable QB, but nothing special. We've had our share of those for the last quarter of a century. I doubt you can go one more in a row, but it would be nice.
