I’m more than happy to chat so thanks for starting the thread. Have a great time over the weekend too, Sunday’s stage certainly looks like a good one to watch that’s for sure 
At this early stage I don’t think anything’s for certain just yet as crashes, illness, positive covid tests may play a part in determining the final outcome.
That said, I can’t help but feel presently that should the main players remain healthy it’s hard to see past Pogacar as the eventual winner. I’d also hazard a guess that both J-V’s duo of Roglic and Vingegaard will join him on the podium ( as per the betting odds ). However, if I was going to place a bet I’d be tempted to go each way on Vlasov. He’s been on great form this year and would have likely won the Tour de Suisse if not for a positive covid test.
As for J-V and the potential rivalry between their star riders. I think they’ll ride as a team, as per the Dauphine, unless something untoward occurs of course, with Van Aert providing super domestique duties for their two GC riders. Despite the pressure on Van Aert in doing so he’s such a strong and incredibly consistent rider, no matter what’s required, that he stands a good chance of taking the Green Jersey too. No doubt, things will become more clear cut once the incredibly tough Alpine stages have been completed though.
As an aside, I’m grateful, for the sake of my liver, that the route this year doesn’t seem to be as wine friendly and therefore conducive to daily drinking either
