Not sure I understand Discovery's tactics on the first tough mountain stage. I heard both Levi and Johan Bruyneel say that the plan was to have Popovych and Contador be aggressive and go ahead and have Levi ride steady, it's a 3 week race blah, blah, blah.
In the LA days, the whole team would have been around LA; if he had a bad day, they had a bad day. He would never have been alone, unless the rest of the team was behind him.
Seems to me Discovery is making Levi prove himself at the Tour before they will throw their full support behind him.
