I find the speculation that Thomas could leave Ineos for ... Qhubeka ... to be interesting. He's still got a lot of firepower, and if he doesn't insist on GT leadership he can race and win for a few more years. I guess the only issue is whether a pay cut at Ineos and potentially a reduced role is better than maybe more money and tour leadership (but much less certainty) at another team. If he did go to, say, Qhubeka, he'd be able to top 5-10 so long as he stays upright, even without any real team support. But he'd need Ineos-level domestiques to aim for a podium.
I'd personally like him to stay at Ineos but have another crack at some of the northern classics as well as some week-long races, then go to the TdF as a super-domestique and third option but without pressure. But I suspect in his mind he has unfinished grand tour business and still should be a protected leader. Unfortunately it's just largely been bad luck for him in recent ones...
