I guess it's assumed Danny R is out next year no matter
what he does the rest the year. If Max moves which I find
unlikely that would throw a wrench in the works. Carlos
deserves a better seat than what it looks like he'll get
Certainly the driver market has a lot of room still.
I do find it interesting that people seem to pick Bottas over Ricciardo. Based on current performance, it's hard to say who's the better driver, and who would bring more to a team. They're both race winners. They both have strong fan bases that can bring in sponsors/media attention.
If I was running an F1 team that wasn't expecting to win, I might be more inclined to pick Daniel. He's got experience with more teams, and could be a constructive figure in what to do (and what not to do). Bottas's time at Williams and Sauber probably doesn't help a team with aspirations, and his time as Hamilton's rear gunner probably isn't as valuable either (although it can be noted Mercedes was much better with Bottas than without...)
If I was running a team expecting to win though, I'd choose Bottas. He seems to have a better mindset for that, to handle the challenges that come with being at the pointy end of the grid. Ricciardo out performed a WDC teammate in Vettel, but then couldn't handle having Verstappen alongside him.
