Warning: Possible TDF spoiler as I give out the probably winner of the tour in this discussion.
I've solved the whole AC needs a nickname problem. We can call him Alberto "The Cancer" Contador, as he fittingly is the cancer on the team, wanting to be selfish and follow his own interest on Astana destroying the team unity, rather than Lance who plays fair with no surprises, and follows the team game plan like a good soldier. But just like the cancer in the literal sense, Lance will once against beat this new breed of cancer that wants to spread itself on the Astana team, in the form of Alberto Contador.
Let's talk about Lance's position on the team.
I feel Lance has played fair the whole tour, working for the team as a fellow GC contender at this point. He even helped Levi secure his 3rd straight victory in the Tour of California earlier during his comeback by being a domestique for him. Only reason Lance gained seconds on Contador in stage 3 in the TDF is because Contador fell asleep, and Lance shouldn't have to pay for other team member's mistakes.
I think Contador took offense to Lance surpassing him in stage 3 even though it was AC's own fault that caused him to lose time on him, which is why he attacked on Stage 7. AC felt inadequate and like he had something to prove.
AC is even more stupid for attacking Lance in an early mountain stage. Don't forget that once you push your body to that limit, you are hurting yourself in the long wrong. The TDF is like an energy bank. You only have so much money in the bank at the start of the race. Eventually you will reach your withdrawal limit, and AC is on the road to learning this lesson the hard way. Fact that AC couldn't even pull that much time on Lance also makes you wonder about AC's form..is he that good? We both know that Lance and Evans is better on longer time trials. The 1st time trial was relatively short. Last one is a lot longer. Lance is better on longer time trials, and so is Evans.
Let's not forget that AC could burn himself out on the mountain stages and suffer a bad time trial at the end, especially since there is some speculation of about possible dissention among the ranks due to AC's ill advised attack. So some members may be reluctant to help AC.
Plus you got a pssed of Texan that has been known to overcome any obstacle when he's angry. One of those big obstacles that come to mind is cancer. After cancer made him angry, he won seven tours. With Alberto "The Cancer" Contador making him angry, I fear that Lance is going to unleash the pain on AC very soon. Let's hope Lance doesn't demoralize AC to the point that AC will quit early.
I didn't want to spoil the race for you guys, but that is what is probably going to happen, unless Lance crashes and gets injured.
