Yes but this time it's different. There is no rider able to beat Vinge, even in theory. His is riding the highest possible watts and he doesn't have bad days.
Pogacar is the most talented rider and if he focuses 100 procent on the Tdf/GT GC it would not only mean to race less during spring but also that he would turn into a somewhat different type of rider. As of right now I seem him as a hilly classics specialist even more than a GC rider.
He could sacrifice some of his explosiveness/VO2max for endurance/threshold. At the same time he might also lose a kilo or two of muscle mass. There is for sure smth untapped potential.
Also he could/should also spend some time in the wind tunnel and improve his TT. Being able to keep up with Vingegaard more often when it goes uphill than in flatish TTs while being the heavier rider probably means that his TT position is off.
If Pogacar puts everything into beating Vingegaard than he will.
