A few thoughts.
I seem to remember a much friendlier relationship in 07 when Lance was coaching Contador from the Discovery Channel car for the final TT. Not sure if AC's statement about LA's personality stretches back that far, or since his return from retirement.
I doubt AC will receive much support from Astana, given LA's past history of holding grudges against anyone who crosses him eg. Simeoni, Lemond. That probably goes for the rest of the peleton, given Lance's unbelievable rebirth during the TdF. Looks like he's going to be a huge influence for a long time.
Both of them should keep their mouths shut. Just like in the NFL and MLB, keep all of the dirt in the family. While I found the whole soap opera with LA's coy hints and jabs entertaining, he should have taken the high road and remained a professional. Had AC kept his mouth shut, he'd look like the good guy. Now they both look petty.
It does make for an interesting 2010, as LA will pull out all the stops to keep Contador from winning. Maybe the Radioshack team will carry frame pumps.
