They are in another league, but I dont consider Pogacar a pure climber, Vingegaard can put more time to Remco, Pogacar no so much. It depends the kind of mountains, for Remco high gradientes are a limitant factor, but with less gradient he is really good, and if there is a false flat btween climbs he can recover time. The only problem is his skills descending...Vingagard and Poggi and half the peloton are in another league. It is normal if you came from Football and has a serious crash as he had at Lombardie.
Vingegaard had margin to improve when he apears 3 years ago, and Remco has that margin as he started late cycling. Poggi is not the best of the worl, but he cant improve more.
