I think he's as talented for De Ronde at least but the competition is also better now than it has been maybe ever in de Ronde.He is more talented indeed, but all-round. In this specific races (classics), he isn't.
I also think Roubaix is more different from De Ronde now than it used to be.
And I wonder how much mass and muscle really matters in that race given that nobody light really races it, and the only thing that really seperates it is that it is not built around 1-3 minutes W/kg surges that basically select the winning candidates for nearly every other race.
