CF, if attacking in the mountains isn't good strategy, then name a Tour winner in the last 25 years that sucked wheels and won. Look at the first two places in the last Tour, Ras and Contador, the most aggresive riders, with the possible exception of Soler. The ONLY person in recent memory who won without much attacking was Indurain, but he was always in control of the race, and never sucked wheels. He was also subtle, and would attack without people realizing it. One thing Indurain NEVER did was suck wheel. The difference is Indurain was true class, while Evans belongs in a sport like synchronized swimming.
What makes someone a wheel sucker is never taking their turn on the front, and dorks like Evans are the ultimate tools because they suck wheel the whole race then sprint at the finish - clearly showing they still had plenty of energy to give. Face it, Evans is a tool. I hope he never wins a race.
Also, there's a lot of talk about podium finishes. Cycling is all or nothing. Either you win or you don't. I can name all the Tour winners for the last 25 years, but don't give a rat's ass about who finished second.
