This is really getting boring. So much excuses (sorry, observations). Before Catalunya Remco was set to destroy Rog according to Remco lovers here. In the middle of Catalunya Remco will destroy Rog on long climbs they said. None of that happened. Now we wait for Remco to destroy Rog in the last day of Catalunya.
If that won't happen, excuses continue towards Giro where Remco will demolish Rog in climbs and TT for sure.
And yet day in day out, some washed 33 year old washes the floor with world nr. 1 rider (Pogačar laughs in the distance).
If you saw Tirreno, and i bet you did, you should have noticed that Roglic was far from going stellar at that moment. (slower TT than Almeida). 2 weeks later he is posting 6.9W/kg on a 23minute climb.
So yes, if roglic had real troubles in Tirreno, than he would have been dropped by Remco. The fact that it didn't happen is a valid observation now and this was not a prediction before the volta started.
The fact that they are both posting numbers seemingly higher than the magic duo in PN is also something we can see. (whatever the arguments are for those higher numbers, or excuses as you call them).
I think you have a hard time grasping some english words, maybe you are, just like me, not a native English speaker.
excuse:
seek to lessen the blame attaching to (a fault or offence); try to justify.
prediction:
the action of predicting something.
"the prediction of future behaviour"
observation:
the action or process of closely observing or monitoring something or someone.
Before catalunya = prediction not excuses
Before giro = prediction not excuses
Prediction that didn't end up happening are not excuses.
Excuses are when it was said Remco would have won the 1st stage if he asn't put out of position, or started to early or ...
Observation are when it was said, remco was badly positionned in that sprint.
Excuses are he lost in the uphill sprint because he went to early, otherwise he would have won
Observation: he went early and blew up.
See excuses and observations can be close together because what we observe can be used as an excuse for something. But you need to observe something in order to grow/understand/...
Observations are typically a statement of fact, something that can be seen
Excuses are typically a use of observations to justify a failure or give a subjective value to the observations.
