PN is history and little could be transferrable to the Dauphine except Matteo Jorgensen's strengths as real. He won't be able to sneak away on any efforts that will get much time. Everyone else should be riding near their best as the Tour is up next. Having said that it's not inconceivable that someone like Roglic actually would ride for a teammate but also make a statement ride or two for confidence. He's won this before and now seems to have his entire season set on a Tour. Bora does need a team defining race to bolster that Tour confidence.The Roglic on Bora at PN seems like there were problems, but then he won the TT at Itzulia before the big crash. He has had the least compromising prep for the Dauphine-Tour sequence. If he doesn't win the Dauphine then age is creeping up on him.
If they do race for two leaders Remco and others will be the beneficiaries, IMO. They'd need to sort that out early if it were a true strategy.
