Okay. I think you underestimate Hindley, and I don't see the value in additional climbers. Van Poppel and Haller are better support than Martinez after the Giro.
The optimal outcome for Bora is Roglic sucking wheel for 2,5 weeks without getting really badly dropped by the other contenders. Then the last two stages with a TT that fits Roglic really good could be a chance to get into the race for yellow.
That's the best outcome because it's more plausibel atm that Roglic will get badly dropped or crashes...in that scenario more moutnain support won't cut it.
So the tasks for Bora (I dwon't use their new team name) is to avoid crashes in flat stages (van Poppel, Haller), have good positioning at crucial points (jungels, Denz) and be present in break formation stage to take pressure of the team. So Vlasov and Hindley could be good enough to go with a Ayuso, Pidcock, Landa or Jorgensen in a break formation phase in the first week.
If Boras has to make the race early on in the mountains then they are probably already in big trouble.
I think the selection is ok. Kämna is obviously missing...even to go for stage wins ig Roglic doesn't work out. Martinez and Lipowitz could be reunited in the Vuelta.
