I might actually agree with you in saying Bernal's GC achievemnts this season beat those of Roglič. Also I don't think Roglič is the best rider in the World or anything beacuse he's leading the UCI ranking, PCS ranking or whatever (I have Alaphilippe as clearly the best cyclist in the World this season). But I have a problem with people saying that the Vuelta field was that much weaker than either Giro or Tour. And I'm talking only abouy GC riders, leaving aside sprinters, classic riders and other domestics. It was weaker, but not by as much as some of you want to suggest.Talk about serving an agenda. I have no issues with Roglic, i even quite like the guy. I do have issues with insane statements as if winning the mighty UAE or Romandie are reason to put him above the winner of the TDF (who won 2 other far more prestigious races than UAE or TDR). Or claiming the opposition in the Vuelta was on par with that of Giro (where he came up short) or TDF. This is simply becoming satirical at this point.
And you can't prove it. Saying "Look at who was second, a 39 yo" doesn't prove nothing. We all know it's not a normal 39yo we are talking about here.
