Sean Manaea, can we get him back?

I read an ESPN+ article yesterday that says the A's are one of the teams to watch in the off-season free agency market. That it has been stated we are looking to carry a franchise record $100M payroll next season. A) do we believe that? B) can we attract players to Sacramento? C) rightly so, it mentions we need pitching the most, who else would be a good free agent besides Sean Manaea? And, D) I'll be stoked if we get Sean back, his regular season pitching is solid, his playoff pitching seems to have taken a step forward with the Mets, and I know there's always hope each season, but it's doubtful we'll make the playoffs anyway, so are y'all excited to potentially bring Sean back, or not?
