Valv. (Piti) tops UCI World Rankings; Riders caught by biological passport named

Well, what do you know! Dear Valv. (Piti), who's DNA has been found to match blood bags stored by Dr Fuentes of Operacion Puerto fame, is now leading the UCI World Ranking (Valverde Tops UCI World Rankings | Cyclingnews.com), despite suffering a two year ban in Italy as a consequence.  Meanwhile, Jan Ullrich, who's career was terminated after his DNA match must be wondering "what if"... In separate news, Cyclingnews.com also reports three riders that appear to be manipulating their blood, at least on the basis of the "Biological Passport" (UCI names riders snared by Biological Passport).  Apparently the three are Franco Pellizotti (Liquigas-Doimo), Jesus Rosendo Prado (Andalucia-Cajasur) and Tadej Valjavec (Ag2r-La Mondiale, and their teams are not pleased.  Disciplinary proceedings are "requested", but it's not clear what these "disciplinary proceedings" will be. So at least the UCI would appear to be making progress in the battle against doping in cycling, but it does always seem to the three steps forward, two steps back.  I wonder what's going on in other professional sports?
