Wiggins needed another 2 kms worth of a domestique and it would have been a bloodbath behind him. Either way you would think that he is a dead cert for the tour now. However he could take time out of the GC guys on stage 5 and get a little ambitious, and there is no way Froomedog wants that.
The tailwind at the finish apparently put a spanner in the works, but you'd think these days that information would get fed back, so it has to be chalked up as a miscalculation.The peloton either completely miscalculated or no-one wanted to help Cav and co. reel in the break.
