The most interesting part of the ruling for me was the decision by CAS not to annul any of Valverde's results prior to 2010 due to there being no evidence these results were obtained through a doping violation. I agree with this decision in principal as the suspension is based on what happened during Operation Puerto. It is clear now that there was widespread doping being practiced in the peloton during the years surrounding the Puerto investigation and it is clear Valverde was one of the riders involved, however it is possible with the improvements made in testing in the past couple of years that Valverde has stopped doping and has been riding clean.
The statements made by Floyd Landis have called all of this into question for me, particularly the descriptions of how the combination of blood doping and micro dosing were being used to beat the testing. Before this I was inclined to believe that while it was likely there were still a certain number of riders still doping, the numbers had dropped significantly since the Puerto years in light of all of the progress made with the testing in the last two years (particularly concerning all the riders caught by the CERA test). Floyd's statements have raised significant doubts for me that Valverde and anyone else are currently riding clean, I'm beginning to fear there may not have been much change since the Puerto years after all.
