About as much as could be expected from them. Thor usually wins a stage in every Tour he enters, so no surprise to see him pick up 2 stage wins here. Cavendish usually ****s up his first sprint in a GT, so again, no surprise to see Tyler winning a flat stage. They had one of the best squads for the team time trial, so no surprise that they won it. They were even a bit lucky with Bernie crashing at the start otherwise HTC would have probably won.
So no, I'm not surprised at all. The manner in which Thor won his stages was perhaps surprising, but let's not forget that it was from a break away both times
Can't believe so many people think Garmin did better than could be expected. Sure, they screwed up the classics, but this proves that it's harder to win a classic than it is to win a stage in the Tour de France.
