You could make a case for 2, maybe 3 riders but MVDP is the favourite.. The first to go are roglic and remco.
-Roglic very consistent but his wins aren't as big/dominant as the others and he never looked like a dominant rider apart from the sprint in GP Emilia.
-Remco is a great champion but he missed too many of his big season goals, often by quite significant margins. He was outperformed in stage races and classics by multiple other riders on the list.
Then you have vingegard, Van der poel and pogacar. I would give it to MVDP, you could make a decent case for pogacar, and perhaps even jonas
-Van der poel won 3 of his 4 big targets and then went on holidays. When they are all big classics, this is a ridiculous success rate. He was dominant in all his wins, always attacking without fear, always making a show, honoring the sport. The only case against him is that pogacar beat him at flanders. But MVDP took his revenge comfortably at Sanremo and worlds. Throw in Roubaix and it's maybe the classics season of the 21 century.
-Pogacar's run of Paris-Nice + Flanders + Amstel + Fleche is one of the most ridiculous demonstrations of racing prowess I have ever seen. He beat Vingegard at his own game, then beat MVDP in a historic edition of the biggest classic. Then he made amstel look like a gran fondo he snuck into and destroyed all the puncheurs in fleche. The problem is that, since then, his only big win was Lombardia, and as
@topcat said back in July, they might as well have given that race to him already. He also got pretty badly humiliated by Vingegard in July in the most famous and broadcasted race of all.
-If you really valued stage racing, and particularly le tour, you could give it to Jonas. But I don't think you can give velo d'or to a rider who refused to seize his (what could be his only) chance to ddo a historic tour + vuelta double, instead parading his gregario around as a winner. Everything about that la vuelta was horrifically awkward and the 2023 season should not be associated with it. I also think that in the modern era, where we have riders like pogacar who are at merckx level, just being le tour winner doesn't carry is a much weight as it did 5,10,15,20 years ago. I'm also not sure that tour + daupine + Itzulia + gran camino + vuelta podium is on paper any better than Giro + tirreno + catalunya + Burgos + Emilia + vuelta podium. Although Jonas's wins were far more dominant and his performance far better.
MVDP Velo d'or 2023.
