I don't agree he was the strongest guy like you say, and I therefore don't see this as an significant improvement. If he had been in a break that got handed 50 seconds due to tactical circumstances in Romandie last year, he would also have won that race. I'm also not sure he would have won PN if stage 7 hadn't been altered, but we'll never know.
The way I see it, he proved last year that he both had talent across different terrain and that he was willing to work hard to reach the highest level possible, and I think those qualities matter more than him now riding for Visma.
