Did you ever watch cycling?
The stage at Briançon is where Soler won in 2007. Contador counter attacked and was going to catch Soler, but he had a flat tire and was reeled back in.
Alpe Dhuez stage WAS a classic. In modern cycling those long range attacks are practically impossible because the control in the peloton is stronger now, but to say Contador has never done it is completely false. He also did it in the last stage of the 2009 Paris-Nice.
Besides, if Contador didn't ride the Giro he'd have destroyed that Mr Nobody of yours. And Contador climbed faster than Pierre Rolland up Alpe Dhuez, if you didn't know.
You yourself can't even hold Contador's wheel on a little hill like the Poggio let alone a climb
Give Contador a Grand Tour with mountain stages like in the 70s and you'd see something else.
Guys like Lucien van Impe performed only well at the Tour and sometimes a different GT. Contador performs well the entire season.
