It would be nice to see a Grand tour contender win the worlds road race for a change, the TT seems to be the favorite for them if they even give it a shot. It seems like it might be a bb issue (as in "the secret race".)

It could be that the "bbs" have become risky enough that they only use them when they absolutely need too.
does not make sense. you only come into the city where it is hosting worlds in the previous week. So you would have infused your bb. There is no chance of getting caught.
you did not appreciate the inverse. The GT riders, with their doping programs and bloodbag deliveries from a new batch of motomen, or motoCound, are able to weed about most of the competition, and it is only the GT contenders who are getting the great advantage of the more advanced BB blood vector doping.
And the Worlds, everyone has access to this benefit, so it is a much flatter race in terms of neutralising advantages accessible to few.
