I would sign-up for him doing a Roglic, have career that last another 10 years and one TdF victory when all stars allign. I also think his TT speciality is something he should keep focussing on and one day go for that hour record. He has a great career sofar and a great career in front of him. Trying to come closer to Pogacar and Vingegaard is a good thing as long as he sees it as a challenge and not as a 'must' to have a satisfying career. He needs some calmness in his head, some Roglic-level "zen". If he can do this, let things go and just focus on maximizing what he has under control, he can be better than ever before.
Not sure if Remco can beat the 1 hour record. And if he does, it's only cause Ganna was not in his best shape when he set it. I think a big guy around 1.85+ cm is better suited for the 1 hour record.
