PR can be won by a bunch of guys because its not a race hard enough (unlike RvV) to make a huge difference with attacks, especially when you consider Phil,Mat and Aert will watch each other, it could be easily gent wevelgem situation and random dude wins and by random dude i mean of course mads pedersen
any other race with a clear obstacle (cobbles,hills,cobbled hills) its very hard to look past those three - they will probably also win Milano-San Remo if they attack, only races where none of them is gonna challenge will probably be Lombardia (too late in the season especially with olympics), San Sebastian (often overlooked by biggest names because of proximity to TdF), Amstel (thats a maybe, depends how tired are they gonna be after cobbled spring, they might skip it in favour of L-B-L) but as long they are present and commited only internal fight between them can stop one of them from victory
btw in his last like 15 stage races, the worst finish by roglic was 4th so even tho he is always around and probably should be the biggest favourite, he is not the best climber and seems to fade towards the end of GTs, while pogacar has really only one extreme performance (TdF TT) otherwise he also doesnt crushes the competition on regular basis (of course now that i wrote it he will destroy Prato di Tivo and i will earn "this comment aged like milk" from resident jokers)...but with lack of competition because dumoulin is out, bernal has back issues, thomas/froome (too old???), evenepoel (too young???fear of stone bridges), Tao Hesjedal (wont compete just against Jay Hindley) it might actually turn out TdF and Vuelta will be between our two favourite slovenians
bennet seems to me like the best sprinter, ewan is apparently going for all three GTs so how will that affect his perfomance, but besides him, bennet doesnt have a lot of competition as Ackermann is rarely performing consistently, whatever Gaviria had, he lost it, there is a bunch of B+ sprinters who can have a good day and win a wee stage but bennet has to be the biggest favourite in every flat terrain
