I've always thought Sagan was the best rider in the field when it's too hilly for the pure sprinters, yet not hilly enough for all the climbers. But it seems since the TDF last year he has lost a step. Yeah, he still manages a top 5 most of the time if he's sniffing the lead with a few kilometers left, but used to he'd just outpower them for the win when near the front. Seems as if he just can't do that anymore.
It'll be interesting to see if he can regain that form again, or if time has truly passed him by.
