I just rewatched Flanders 2016 and it was so weird to watch the race. Cancellara is literally just sitting up when Sagan, Kwito and Sep attack and relies solely on Stijn Devolder to keep it close before Kwaremont. Had he been stronger, no problem, but he needed a more extra percent and therefore couldn't catch Sagan. He definitely would have had a better chance if he acted differently instead of only thinking about last time up Kwaremont.
Greg's two best seasons were 2016 and especially 2017. I think he would've won the ladder, but he got unlucky both years where he was the biggest favorite along with Sagan. He was soooooo good in 2017, was undropable for peak Sagan and was a complete menace in the sprint in small group sprint. I definitely consider peak Greg a better cobbled classics rider than Sagan, but his true peak was only 1-2 seasons, and he really wasnt the same before or after, although quite consistent.
Sagan would have murdered him and Naesen on the Paterberg.
Okay, maybe not, but damn that 2017 Ronde was a frustrating experience.
