Roglic had a far superior team in 2020; Pogacar didn't have a team and won the Tour in his second year as a professional. There was a glimpse of a Tour winner, even though the team was crap .
Remco in 2024 at least had Landa and finished at the same distance as Daniel Felipe Martinez in the Giro, Pogacar in 2020 didn't even have a domestique like 2024 Landa.
