Jumbo has a chance against Poga. If they seize that opportunity and move away from their current "Roglic" system.
Both Roglic and Vingegaard are individually not strong enough to defeat Pogacar.
Although I think that Vingegaard will not have to be a lot inferior to Poga at best. Both have to attack again and again. Roglic on shorter climbs, Vingegaard on longer climbs. But then they both have to be able to accept that this can be at the expense of their own winning chances and even podium chances. But I don't think Roglic would want to do that. Roglic hardly ever works for a teammate. Or not thoroughly or for a longer period of time. Cfr the lack of support to Van Aert in different occasions. I don't think Roglic will give up his chances, however slim they may be, to see Vingegaard finish ahead of him. In addition the team management has never shown that they are not conservative and/or go against Roglic. So Pogacar remains the towering favourite, although Jumbo Visma has all the weapons to beat Pogacar
