If Roglic were to my delight win a TDF or Giro it could be named the Better Tony Rominger.
It would be beautiful but I don't see it as a "necessity" for his legacy tbh. I mean I've seen a few articles pop up over the last 24 hours in which there's a "no Tour de France, no glory" conclusion, such as this one:
Primoz Roglic: Where does Vuelta a Espana champion rank among the greats after third win? - Eurosport
Not to denigrate a race that is loved by so many, but one Tour de France is worth… I don’t know how many Vueltas. More than three, anyway.
I can answer this point in several ways... including by pointing out the names of Tour winners from the past 20 years & comparing them to Roglic on the "glory" spectrum:
Pogacar
Bernal
Thomas
Froome
Nibali
Wiggins
Evans
Schleck
Contador
Sastre
Pereiro
Lance
I have my own bias but in terms of "greats" on that list, Roglic is with Nibali right now & just beneath Contador & Froome. He has the rest beaten (including Lance for other reasons). Pogacar is an ongoing rivalry so things will evolve there.
And I also consider the actual performances, style & behavior to be relevant as well, i.e. when riders such as Roglic perform extraordinary feats on a bike & behave in a way which people like, it creates a long lasting impression which dwarves statistics (i.e. it's quite easy to imagine a few names on the above list getting stomped pretty badly by 2021 Roglic... both physically & humanely).
Other aspects to consider:
- Roglic goes for the win in every race he enters, so his list of one week stage race victories & exploits during the 2018, 2019, 2020 & 2021 seasons matter.
- in 2021 all races are televised (viewable via streaming as well) & accessible. So the monopoly of the Tour on exposure is lesser than previously.
- we're also in one of the most competitive eras where teams fight tooth & nail for a slice of the world tour cake. This means previous eras where riders who would use pre-Tour races (or even the Vuelta) as form building exercises for the bigger prizes are no longer the norm. Winning the Tour of Basque Country (for example) has become in & of itself a real goal. The fight is everywhere & Roglic incarnates that modern aspect of cycling best, i.e. just look at the intensity of his defeat in Paris-Nice (riding to the line bruised & injured even when all was already lost) or the massive fight in Itzulia versus Pogacar. These were real prizes targeted by the world's best riders.
I only post about this because the inevitable conversation about "all time greats" aka goats usually overlooks some important factors, i.e. namely the fact a rider's fame & renown isn't dictated by numbers on his Wikipedia page.
In public perception I assume Roglic is mostly viewed as someone who has massive setbacks but always comes back stronger & wins massive prizes with the best ability to bounce back from disasters in cycling (& arguably entire world of professional sports, everything included). So to answer that Eurosport article I previous quoted above, I'd say that is already worth more than 1 or 2 Tours.
