The only comparison between Lance and Schumi is how high they have set the bar in their sport. Other than that its two worlds apart.

Lance besides from a great athlete has shown such a great human persona, striving against (and defeating) cancer. He just seems such a likeable guy. The ads he is making for his bike team on Discovery channel are just hilarious.

On the other hand, imagine what the reaction would be if Schumacher invited Rubens Barrichelo (or any other of his teammates) for a night out in town :)
