RownhamHill said:Probably an elementary question I know, but why wouldn't five chasers work together to get him back? Is it because the other four can't see any point, as it would let Sagan win?
If you're alone there's no reason to hold back anything, if you stay away you win. If you give 100% in a group the others (who will probably hold back a bit) will beat you in the end. So you need to keep some reserve for when Cancellara gets caught
Combine that with the fear of Sagan and the fact that Cancellara probably handled the effort so far better than anyone else and you get a situation where only a Fabian implosion will cause him to lose today.
