You could also compare Pog to Greg Lemond, who despite having a shortened career also showed talent in a lot of different races, and a similar will to win in the big ones. (albeit it was a different era).
Vingegaard is a classic pure climber, who I think needs a strong team around him. He doesn't have that this year. But I bet with a few more kilos and a different focus he could win LBL and Lombardia.
For me Pogacar is the perfection of a new breed: the climber who is good enough to be a classic rider also.
Merckx, Hinault, Lemond, they we're powerhouses who just battered the climbers. With the heavy bikes, long stages, lesser preparation and teammates, in thoose days you just needed the extra kg to survive 3 weeks of grand tours.
Then came the Epo TT riders heavyweights who could suddenly climb to, Indurain, Rominger, Ulrich. Remco would have ruled supreme in those days. Van Aert would have been a GC contender in those days.
Armstrong reversed the trend, lost weight but kept his TT credentials and acceleriation. Still Epo fueled, but Froome was basicly the same, only EPO was replaced by supreme professionalism and teammates.
Also the fact that ITT were tuned down and MTF stages are more popular with TV viewers favors the lightweight climber.
