Not the easiest sprint/crash to get a read as cameras miss a lot of the movement, but some notes I made :
1) OK, Pippo owned the blame for himself so I guess he was going to crash anyway. However, Goss selects an imbecile line to a corner!!! Slows down a lot and tries to perform an outside-inside sweep in front of whole pack. Terrible maneuveur - shoulda just stayed on Impey's wheel. After all, Daryl did not have a problem to get through...
2) The corner would have played a major role even without the crash. Compare the position of Kristoff vs. Ventoso entering the corner and right after it... Kristoff makes it safely thru' in the 3rd spot but goes too close to barriers and has to slow down losing all the momentum. Suddenly he is trying to accelerate again with at least Schorn & Caruso having passed him easily.
OTOH, Ventoso may ENTER the corner quite far away but comes out of it in 6th or 7th position having already passed many other riders than just crashees...
3) Right read in that corner was to go inside just fast enough to keep the line. I just can't see how the people trying to come around outside would have had a chance in this one. EVEN without a crash, you were bound to be forced to brake as some people from inside would swerve outwards due extensive speeds and cut in front of you while forced to slow down to avoid barriers (see Kristoff)
4) Yes, it was a dangerous to put such a corner at 350 m. Still, one was able to do it in high speed (see Impey, Nizzolo, Caruso, Ventoso, Schorn) so I don't think it was OUT of PLACE one anyway... It was just that some people were overly aggressive (Pozzato), some were absolutely mindless in their line (Goss) and some others read their approach&positioning absolutely wrong (Maes, Haedo, Cavendish). Renshaw was unlucky to get caught in-between Pippo&Goss. He had read the sprint very well...
So, my 2 cents is that IF this was just a straight sprint - yes, Cav was close enough to likely win again.
But even if not victim of Pippo/Goss crash, the outside riders would have been clogged to a standstill speeds by Kristoff (effect worse behind than for the rider causing it) and have had no chance to rework he speed up in time... These riders were Cav & Haedo.
