I can't watch the Tour at work, but the 'newsflashes' bulletins on le tour website said that Evans dragged the chasing group up much of the final climb so your criticism sounds very harsh.
eg
17:28 - Evans At The Finish...
Evans has finished the stage 2’17" behind Piepoli.
17:21 - Menchov Moves Forward...
Evans has been leading his group most of the time for the last few kilometers. Menchov did more forward briefly but now it’s Evans again.
17:18 - Three 3km From Finish
Cobo continues to lead Schleck and Piepoli. They are 3km from the finish and one thing is virtually certain: Piepoli is preparing for a mighty attack. He’s been following his team-mate and the virtual leader of the Tour de France, Schleck, for the past two kilometers.
Evans is setting the pace for the next group (that’s 1’55" behind) and stuck in the middle of Schleck’s trio and Evans’ septet is Efimkin.
17:02 - Regrouping...
Evans has been caught by Sastre, Vande Velde et al. The surge didn’t last long and now Ricco is attacking.
17:01 - Evans Attacks!
With Kirchen climbing back near Evans group, the Australian has attacked. He has caught Astarloza.
16:56 - Evans Dropped
Evans is now out of the saddle and riding alongside Menchov and Sastre while Frank Schleck leads the stage under the 10km to go sign.
