I think Contador's consistency, throughout the year, is what distinguishes him from an Armstrong though.
The Texan peaked once a year, this was likely because his natural ability together with his program only acommodated one peak per season.
By contrast Contador wins practically wherever he goes, throughout the season, in GTs and in secondary stage races, whereas when he road those couple of classics last year that suited him he was up their at the front with the specialists.
Now you can say what you want about the guy, that he's a doper (in a doped field however, at least now among the brunt of his main competition - if it were 5 years ago, nearly everyone, but perhaps even so still today), but he is a real and extraordinary talent.
I'm all for punishing him if that's what the decision is, though this won't alter the fact that what he has achieved, was able to achieve, was not merely the product of chemicals, but a natural class that potentially will make him the greatest stage racer the sport has ever known. Winning not just in one month demonstrates this. Nor do I make excuses for him, but the stage race champions have the greatest overall capacity and the most efficient engines of the group.
On this account, therefore, I don't comprehend a certain animosity towards him. His class is authentic in a sport, however, which is not.
But if everyone were clean, I believe he'd still be the best. I don't think this could necessarily have been said, though, between 1991 and 2005.
