I read/heard a couple of strategies last night that are total opposites of each other and both made a lot of sense.
First is the commentary from Coach Carl (http://www.coachcarl.com
), he basically said that the tour is laid outto suit somebody other than the USPS and that the tactics of the team aren't working out. The team tactics have always been to drive the field with LA in tow, to drop most of the field, then once you get to a critical part of the stage, LA takes off and drops the few stragglers and takes big chunks of time from his opponents. This hasn't happened this year as we've seen. We see USPS setting the pace, but not much else.
Then it was the pre-race commentary by Phil and Paul on OLN, they basically said that Lance hasn't looked like himself, but he also said that USPS and LA has not yet once attacked, yet LA is still in yellow. Basically saying that they are doing just enough to stay in yellow. And it's obviously working, Lance is still in yellow and hasn't had to truly work yet.
