He may have, who knows, put him in a Worlds TT against Cancellara Martin Wiggins Grabsch Phinney Durbridge Dowsett and he wouldn't beat them, a long technical hilly TT after 8 days does not exactly provide a great reference point on pure ability. Wiggins went from a strong TT'er (never winning an elite long one) to a completely dominant one in the space of an off-season at a time which people believe is after the date he commenced doping, so it's not like his TT improvement can be down the the discovery of EPO for the first time. Same for Contador in Annecy.
And no, Evans was no better in the Giro than he was in the Tour last year. Not in the first week at least, where he was very strong in the Tour.
