I could see this getting real messy with Sky and Skil Shimano inadvertently helping one of the 2 (or 3) main protagonists to the victory.
For example, Sky may try launching Kennaugh and/or Cummings into a last 10km attack, which will be doomed for sure. The true sprinters team will be forced to chase for the stage victory. Sagan and Liquigas are able to catch a free ride to the line where he pops out, grabs third place, bags the 4 seconds and the overall victory.
Eurosport Asia must have thought it would have been all over by stage 6 as today's stage is shown 10 hours in arrears. Grrrr. I pray the live streams work. They often break up in the last few kms when everyone tunes in.
