The riders would wait until the race settles down and then chose between plan A and plan B. Plan A would be if the riders find that Lance is just too marked to be able to make any moves. I would use him as a diversion and race for one of the other riders. The trick is that you would make the other teams think you are racing for Lance and slip one of the other riders like Tyler or George up the road while the other teams are watching Lance. Plan B would be that, if either Lance is not too marked or plan A free's Lance up, then you race for Lance. This requires team flexibility and very few teams are coached to have this kind of flexibility.
Most teams have a very rigid structure and become surprisingly predictable.
As I have stated many times, I go to a race to win and winning means keeping your competition guessing what you are going to do. If your competition figures out what you are going to do, then they can develop a counter for that strategy. To counter this, I used a number of different approaches. First, if I could figure out before hand what my competition expected, then I would use their expected strategies and tactics to develop my new racing strategy. In other words, I would use their own strategies and tactics against them.
