From last years time trial to this years time trial schumacher had over a 4 minute turnaround in the last time trial (He was 2.26 back of Evans last year), this is with him being on the attack each of the last 4 or 5 days? I always give every one a benefit of the doubt, innocent before guilty, but this is just way to hard to even fathom.
LIke it has been said, I think it was more about Cadel riding that bad, more then Sastre riding that good. Sastre compared to the other riders isn't that much more exceptionally, he rode a little better which is believeable, just Cadel wasn't good. He never looked comfortable, he was riding with mouth wide open within the first 5 km, trying to scrounge for the power.
