For TJV i would say they are in a rather good position. Whenever in doubt, Roglič is the captain. If for whatever reason Roglič won't deliver, plan B is i guess still a really good one, for TJV.
Team INEOS, here i don't follow everything all that close, but somehow i feel that Bernal is not happy. He likely wants to have the same status as Roglič (at TJV for the TDF 2020), or at least for being able to go to Giro first. And somehow i feel Bernal likely won't get any of that. Froome is a big unknown. Will he be able to get in a shape, to win a Tour, or not. I wish him all the best. As for the Thomas. If he will prepare well, winning the Tour will likely be the only thing on his mind. I doubt Thomas is prepared to help Bernal in the same way, he did that for Froome in the past few years, or until that point, when he has decided it's time for him, to win the Tour.
