3 consecutive wins at the WC, 5 consecutive green jerseys that should have been eight. More than 10 TDF stages. At least podium in every classic except Lombardy.
Plus one of the major factors defining Sagan. Not a grey mouse like most of his competition.
Consistency should be key and in that aspect Sagan is the most complete rider.
Sagan doesn't have a podium at Fleche Wallone or LBL.
