He’s got more Giro and Vuelta wins than Armstrong and two more TdF victories than Lance had at his age. I’d say the chances are good he could eclipse Armstrong.
Like I said...let’s see if he wins six in a row.
Possible, but not likely. There have been other riders who reeled off multiple Tours in a row. Contador has a way to go before he can even be mentioned in the same breath with those guys.
But I take your point about the Giro and Vuelta. It's those races that are a drag on Armstrong's reputation.
