Never know if others will come through. Also depends if andy is content coming second to bertie in tdfs rather than going for giro / vuelta to get at least a gt under his belt.
Aero. Both get busted and Denis Menchov gets his third podium and second win via another's doping.
Actually, much depends upon the teams each ride for. I could see an Gesink or Brajkovic or Nibali or... with a USP/Disco like team throwing a wrench into a weaker Astana or Schlecks new team.
