Perhaps the first post should have said no-one should comment who has not raced as a pro, and knows what actually goes on. Which the poster clearly has no idea about. Hindsight is a wonderfully exact science. Criticism is easy, good alternative ideas are harder.
The race was not hilly by pro standards, made for a sprinter, GB played their hand, and it's reasonable to expect the race to play out like a proper pro race, which it did in a way. Aussies and Germans both had sprinters who were at least podium prospects, but failed to ride for them. It did look, as a friend put it, "as if the rest of the peloton decided that a TdF win and World Cjhampion was all that GB were going to get", so rode against them, even to their own detriment. The only thing they didn't see coming was who would win, which was not the best result for anyone except an unrepentent Kazach.
Silly comments about DB, he has constructed what is seen as the strongest team (Sky) in the peloton from a standing start in 3 years. That takes commitment, management skill, and vision.
