Havent read the whole thread, but Im gonna put my 2 cents in anyway, so sorry if my points have been raised before.
Of course descents arent too dangerous. The thing is, they need to be carefull where in the race they are. You dont want a peloton on a hard descent trying to get the last people of a breakaway, because in big groups someone is bound to make a mistake, which makes the person behind him make a slightly bigger effort to correct and the person after that a little bigger correction, and so on until someone goes off and other people fall over them. Just like what we saw in the Vinocrash. (Im by the way not saying that that descnt was too dangerous, because of the placing within the stage, the peloton had to make their own choice not to go down fullspeed.)
If you have a descent like yesterday, there are two possible scenarios, or everything would have stayed together and they could take the descent pretty easy, or it could have hapenned like we aw yesterday, with small goups.
And for Andy Schleck blaming the person in front of him slipping: a pro should know in whose wheel he should be in a descent. And he wouldnt be ahead of Contador if he wasnt hold up earlier by someone in front of him crashing, but conscidering the fact that his hypocrisy knows no limits, we shouldt be surprised that that wasnt a problem and this is.
