There is a difference between having a few risky picks (which I do with Vacek, Del Grosso and Bettiol (the latter has been a regret from day one and his outings in Arabia have definitely not changed that)) and not having any of the ten most popular riders.
Yes, as I said there, the downside could be pretty big if those ten most popular picks would all perform if you didnt pick them. You could lose ground, that you wont make back.
But then the probability of all those ten picks performing really well is maybe not as big as one think either. However, probably a high probability that 6-7 of those could turn out very good.
So if you disregard most of the popular picks, one has to have a lot of conviction in other riders and them delivering. Which is easier said then done, but not impossible imo. It becomes really important in how good ones ability is to assess riders that could have great upside, that many are for some reason overlooking, and making a bet on it. A lot of people, in general, probably overestimates their ability to do this and hence picking most of the popular picks is probably the best strategy. Making fewer "own" choices so to speak, but that may not be as fun.
How much one allocates to "popular picks" and how much one should try to find other picks, is definitely something that can be debated a lot. Then one also has to factor in everything that can happen to a rider over the season, which one has little control of. It is not easy.
