Numbers show Pogacar is clearly a bigger outlier. Being the best from a group of 40 professional riders is far easier than being the best from a group of 500 professional riders.
No one can ever tell me this is a high level of cycling:
(There are plenty of more examples of 6/7 Belgians in the top10)
Paris - Roubaix 1973 One day race results
Paris - Roubaix 1973 was won by Eddy Merckx before Walter Godefroot and Roger Rosiers.www.procyclingstats.com
Liège - Bastogne - Liège 1970 One day race results
Liège - Bastogne - Liège 1970 was won by Roger De Vlaeminck before Frans Verbeeck and Eddy Merckx.www.procyclingstats.com
Ronde van Vlaanderen / Tour des Flandres 1975 One day race results
Ronde van Vlaanderen / Tour des Flandres 1975 was won by Eddy Merckx before Frans Verbeeck and Marc Demeyer.www.procyclingstats.com
Any reasonable person can see this was not a developed sport in the 70s. This was a national sport. Specially RVV and PR, those races looked like Belgium national championships. These are facts, we just need to look to the top10 in almost every year.
Even in WC, Belgium had like 10 riders in a peloton of 80 riders (10 teams) and can anyone convince me Merckx's 3 titles are similar to the 3 titles of Peter Sagan. Again, any reasonable person can see these facts and understand why Merckx is just the GOAT for some people because of his palmares.
You don't get it, do you? Only 1 or 2, make it 3 including Vingegaard are competition for Pogacar.
You may include 497 riders in MSR if you wish, but if Van Der Poel isn't in the start list, there's no competition. Okay, maybe Ganna, potentially Evenepoel.
In the same time you may have a start list of 40 or even 20 WITH VDP inside and you have much stronger competition.
Absolutely the same goes to TdF, you may send all the pro riders (say 1000) in TdF, but if you don't have Vingegaard, you don't have competition.
