What on earth are you talking about? Sagan could not get over the big cols in any position to win atop a serious mountain, even from a break, in the races that matter. He was not competitive in a TT, let alone a high stakes one, nor could he win sprints mano a mano against pure sprinters. By contrast Wout has done all these things. I'm laughing.Except Sagan's rear wheel getting further away. Not bad for someone who "As great as Sagan has been, he can't climb, TT or sprint as well ". In those WC he showed they he could do all of those things. If his pursuit escape in 2015 Van Avermaet (who didn't seem to be attacking the whole race while saving himself) couldn't follow him on a hill, couldn't close the pursuit/TT to the finish even with help.
No one could do that at Flanders when he attacked similarly on the hill and digging deep to stay away from the entire field. Capped off by a stellar wheelie of joy. It's worth checking out how lean Sagan was, having changed his physique to suit efforts IMO.
Roubaix was an honest mano y mano ass kicking of the entire field.
Not sure what you guys want but Peter did this for himself during his time not to be second-guessed and compared to riders yet to win anything. Sorry if this sounds "why so serious?" but everyone that casually pimps their favorite rider as the Future Great by demeaning another's actual accomplishments is ignoring the point of the sport. It's hard, you have to endure and finish...then you need to get the result. Sagan's results, like Hinault's, Lemond's and many others are actual and in the books.
Why you bring Hinault or Lemond into the equasion is baffling, becouse neither Wout nor Peter has that type of engine. It's outlandish, other than for comedic effect.
