He's obviously a great talent and probably the best all rounder at this point, better than Sagan and EBH.
Nevertheless, as a fan, he hasn't convinced me yet (not that he has too
): he's seems to follow a lot of the Valverde playbook regarding tactis. Wait for the sprint, for the win or for other place. Obviously he gets a pass considering his ride in Strade Bianchi (not a top level race) but specially because he's a young guy who only took the Ardennes seriously this year. This year the classics were just three bunch sprints so he obviously can't be blamed for waiting for it.
I hope he changes his mentality as he grow up, otherwise he'll definitely be another Valverde. He has great rouleur skills so he should be able to attack from further out, instead of waiting to sprint. We don't need more Gerrans, Valverde types that don't risk a single thing.
GT wise he still needs to improve his climbing a fair bit otherwise he'll be faded to contend for the Jurgen van den Broeck/Brajkovic anonymous top10 placings that annoy the hell out of me. Again, time is on his side, specially if Quickstep doesn't overcharge him with responsability: in my perspective, they took a good approach this year by not letting him ride the cobbles. I'm not sure if it was necessary for him to ride Romandie but well he doesn't seem tired, judging by today's results.
