It's been a few years since Landis, so do you believe Ricco was the only contender doping?
I think there was much less doping this year. I say this because watching the mountain stages, the GC men were fairly evenly matched.
What stuck out for me was riders couldn't maintain the huge accelerations. Frank and Andy Schleck, Evans, Valverde, Kohl - on the twisties of Alpe D'Huez no one maintained more than 30 seconds of acceleration. Of course Sastre put the big hurt on, but he won more because of the uneven tempo of the Schleck brothers more than anything else.
What surprised me was Schumaker's (sp?) TT wins and his solo flyers in the mountain stages... My money is on him as the next positive. How does he spend all day out front several times and come back to win a TT?
Also, Sylvain Chavanel could be another. Seemed like he was in a break every other day... could just be an incredible strong man though.
