Personally I wouldn't quote Mart Smeets when it comes to facts. More importantly: the signing of Ricco has been vetoed because of his passport (which implicates an OFF-score higher than 116.7 (1:100 false positive, and set as limit in most internal doping programs: Damsgaard, Garmin/HTC, Mapei Center) but probably not exceeding the UCI passport limit, which allows to open a direct case...
All we know about Contador is that he has very high levels, but
probably just one
somewhat remarkable (hemoglobin) spike in his passport,
allegedly in May 2010, which
probably has caused him his 'five' - but no further notion in the IO-report. Also he hasnt had any problems in the Damsgaard programs (e.g. Gusev) etc.
On Vaughters. I always thought the deal was more or less sealed, so that he could switch teams right before the Tour. It would probably also explain his pretty strong believe/support in Contador. I mean: he isn't just a fanboy, is he?
