Can someone explain how Basso is getting around the 4 year Pro-tour team ban.  Is Liquigas planning to drop from the Pro-tour or did the ban not apply since he was not proven to have taken drugs just to have planned to take drugs?

I would think that the four your pro-tour team ban would also prevent Vinokourov from joining Astana.  Isn't the ban from riding for a Pro-tour team different from the ban applied by the cycling federation of the rider's country?
