This. Roglic will not be here much more years, specially after his interview talking how he considered retirement after crashed out in the Tour. Maybe 2027 will be his final season.If you want to compare to riders of his calibre - Contador won 8 in 2.5 years after his final Giro win, Nibali won 3 in almost 5 years after his Sanremo win, Jalabert (who will remain miles ahead of Roglic) dwindled to 3 and 5 wins for the year in his final two seasons. Valverde is a crazy outlier in all respects, there is a strong case to be made that he hadn't peaked yet at 35.
And fwiw, Valverde was also better in the classics and racing a win-friendlier schedule in his mid-30s compared to current Roglic.
