....If it is true that those top contenders were guilty of PED's, then this years winner will not have a tainted win, because we dont know how those riders would perform on a level playing field. If, and I do mean IF Basso was juiced for last years Tour, and the Giro, then who knows what he would do clean. Same for Ulle. Maybe they arent so good. So, if Landis, Hincappi, Levi or whomever win, then it is fair, and probably they would best those riders on a clean, level playing field.
That said, please come up with a reliable, fair way to test these riders around the clock so we can be sure. To suspect the winners is unfair to them if they are truely clean. The playing field needs to be level and fair, and maybe this is a good start.
PS. If Vino is clean, and I suspect he is, I feel most sorry for him.
