I think you just have to accept that one-day road racing is not a sport in which the strongest man always wins. Over a season of races, or over a Grand Tour, strength comes to the fore. On a single day, getting in the right break requires strength, judgement and a strong element of luck.
Breaks will always be formed of riders with conflicting hopes and motivations. It's not great if trade team loyalties distort the inter-national competition, but it's a relatively minor factor.
The bar on professionals collapsed in the face of most leading amateurs being professionals in all but name anyway. I think that going back to minor riders that no-one has (yet) heard of would do our sport no favours at all.
We may not have produced the gold in the men's race, but we've had one good race and one brilliant one in terms of excitement, and that can only lead to more public interest in future.
Heck, after the women's race, the BBC's chief sports editor may even know a little more about bike racing
