All depends on how A. Schleck improves in TT.
Don´t see Valverde as GC contender, at least not for the podium, maybe Top5.
Evans, Wiggins, and DON´T forget Menchov. Nobody speaks of Menchov, maybe because Menchov lacks of charisma and is shy of media, but Menchov is my absolute top favourite for this year´s Tour - even more now that Evans has shown that it´s still possible in this age (Menchov will be 34 this year).
For the first time in his career, he´s even been on the track to improve TT position, working with Sebastian Weber who came from HTC. Currently riding Sarthe, he will be back for Romandie and Dauphiné before heading to the Tour.
His motivation is higher than ever, after maybe "losing" one year while being with Geox.
Menchov, Wiggings, Evans, my top contenders for the podium. Kloeden maybe, being in his Tour shape of 2011.
Addings VDB and Basso, and the usual Garmin surprise, Andy and Valverde will be happy to be somewhere in the Top10.
