Bullcrap, bats dos and bollocks! I am a very firm believer in "guilty until proven innocent", but this whole Lance Armstrong thing has sparked a witch hunt. There is no evidence to suggest that the top guys like Djoko, Fed, Ferrer etc. are doping or using PED's.
Until there is concrete evidence, it's just speculation without any merit.
I wonder if its maybe possible to achieve what they have and sustain it through proper nutrition, and their training regimes.....*sarcasm*
...and if it happens that they are doping...well then i'll be very upset.
Highway to...oh look a squirrel!
