Well I think both the organization and teams are at fault for the many crashes in the last few days.
The question the organization needs to ask itself: Can we still send a peloton of 196 riders over these narrow roads with the speed they drive at these days? No.
The lesson teams need to learn: Have respect towards each other. There's too little respect when going downhill. Back in the day of Armstrong and Discovery Channel, Armstrong's team actually controlled the peloton downhill and made sure they all came down in a respectable pace and to avoid accidents. What teams this year are doing is riding downhill without brakes, basically. There is no need to go downhill so fast when the attackers are only a few minutes ahead so far off the finish line.
Anyway, there goes my man Jurgen VdB. Best man of the Tour so far? Gilbert by a few lightyears. It's amazing how he just came to the Tour with the goal of a stage win and a day in the yellow. All of a sudden he's fully going for the green jersey. It's amazing how he's strong every single day and how he even does the work himself.
I suspect him to move to BMC for next year, and if BMC will look as strong as they are this year Gilbert will be unstoppable in what he's best at this year.
Finally the Belgian lions have awoken: Gilbert, Van den Broeck, Deveneyns, Vanendert. It's good to be a Belgian cycling fan this year!
