This is a stupid thread. A monument is incredibly hard to win. It's not like a GT stage where a break might be allowed go while the peloton take the day off - everyone on the starting line wants to win. Added to that the extreme distance and the chaotic nature of racing - I think whoever manages to cross the line first at the end deserves some credit regardless of who they are. There were people saying after this year's Paris Roubaix, one of the toughest, best races I've ever watched, "well it was a good race, but it's diminished by the fact that Boonen didn't win" which I find insane. If you only want the favourites to win then why not just stick everyone in a lab and give the trophy to whoever puts out the most watts over 6 hours.
Take someone like Van Summeren - he's seen as a 'lesser' winner, but he went in a chase group to catch the break, crashed, caught the break anyway, held on through a heap of attacks as half the break were dropped, then soloed away from the group, finishing the last 5km with a flat tyre. That's heroic stuff even before you take into account it happened at the toughest race of the year.
I dislike the style of someone like Gerrans, but these races are the absolute pinnacle of the sport, and winning them is incredibly hard, and a massive achievement regardless of circumstances.
