I think it gets attributed to lockdown but the autumn of 2019 and Roglic's Vuelta win was when I first felt something had changed,
Primoz Roglic poursuit sa moisson de victoires dans les courses par étapes au plus haut niveau (« world tour »). Sur ses deux dernières saisons 2018 et 2019, il a remporté le Tour du Pays Basque, 2 fois le Tour de Romandie, l'UAE Tour, Tirreno Adriatico et la semaine dernière le Tour d'Espagne...

The nature of change feels different too, with Sky and US Postal their programs seemed to lift most riders levels uniformly, with the odd super-responder like Froome, but look at Jumbo-Visma for example, there is such a huge disparity in response. Laporte, Vingegaard, WVA and soon Jorgenson have looked at times like they are riding against children, but Dennis, Dumoulin, Valter, DVB and now Uijtdebroeks look no better or are worse now than they were on their old teams.
UAE don't actually seem to be anything special without Pogacar. Matxin gets credit as some sort of scouting guru but half the users on here could've told you that Ayuso, Del Toro and Morgado would be good before they went there, they just seem to have more money to offer youth prospects and invest in tt-equipment. Flattening Italian Pro-Conti teams might fool the sheik but only really Pogacar sticks out. I'm going with a less-organised more slapdash version of what Jumbo are doing, I'd say definitely blood bags though, look at Pogacar's resurrection on Cauterets, Mcnulty and Bjerg on Col d'Azet was the most obvious case of refuelling I've ever seen in my life.
Whatever they're doing, I would say at least Geriant Thomas and Tao Geoghegan-Hart seem to have figured it out and responded in-kind.
Bahrain in 2021 and even last year on Angliru was also notable, I'll always go back to the Dauphine, I'd love to know what Padun was doing, absolute rocket fuel.
I suspect something a bit different is going on, but it could just be a case of increasing the risk constantly in dialectic with other teams and riders performances.
