To be fair, Cancellara did do what he could to keep the peleton from riding hard and to not sprint at the end of the stage. Of course unlike yesterdays stage, it wasn't one the GC contenders were looking to make time on which made a big difference and the reason for stopping the sprint was clearly in protest at the risk on the stage, as it made no difference at all to the GC contenders.

So I agree with your overall point that it came down to luck as to on which stage and where abouts in it people crashed, I'm just being a bit pedantic about exactly what happened
