I think cycling is probably the least predictable sport in the long term that I know. Before this Tour I saw semi frequent discussion whether Pogacar could win all 3 GTs in a season. Now he's not even the best GT rider in the eyes of many anymore.
I'm not super sure about the predictive value of this year for other years, and I wonder if UAE underestimated the threat of Jumbo.
I don't think there have been many consecutive years with super similar relative levels of the same riders before. Arguably 3 at the most with Contador-Schleck from like 2009-2011 and maybe Froome-Quintana from 2013-2015.
Armstrong Ullrich Beloki for four years.
