Nah...All of them are doped, so Contador is still the best. These kind of guys are the best cycling machines since they are young, so they are selected to receive the attention to really make it to the top. However I still believe that there must be a clean cyclist in the TdF (not sure if he finished 15th, 16th or 23rd though, probably he finished much later). That is a reason enough to put Contador and anyone else doped in a life ban, no matter how naturally gifted they are.
I feel so sorry for that first clean rider, and so many other who did not make it to proffesionals....It's discouraging.
