He could have annhilated Wiggins in the Alps and Pyrenees. No question in my mind.
As quoted above, there isn't really any evidence in races that he can win stages by really big margins, but if that is the case why not let him chase down Valverde and get 20 seconds on Wiggins?
Just seemed a bit silly, and you can bet the image of Wiggins smiling as he crossed the line whilst Froome was shagged won't go down all that well.
Aside from those two though, the other contenders have been blooming awful this year. Evans was way off the pace. VDB never had any legs. Menchov et al were awful, and Nibali wasn't up to much either (and Basso - good god what has happened to him?!?!). That's before getting onto Frank.
Makes you wonder if a lot of those guys are just riding clean now and are showing their true colours.
