One thing I like about Contador is that he can break his opponents with repeated attacks. That makes for exciting racing that is also easier for the public to "get". Guys like Levi are also talented (maybe not as much so) but he isn't as "exciting" of a racer. He tends to do better by keeping the pace steady but very high. This does *not* (edit) usually make for the most exciting reports...
needless to say the next few days of the TdF are going to be fun to watch...
