are you really surprised?
there has to be a reason why a guy that at 24 won an olympic medal being the only rider capable of following bettini on a hilly course leaving behind nobodies like ulrich, vino, valverde and erik dekker amongst others only became an anonymous domestique.
his only shown of talent after that was the 06 vuelta, which happened to be his first GT and still is his best performance ever in a GT.
a friend of mine who knows him says he has the ambition of your average garbage picker

never tried to improve or impose himself in a team.
