Can't see Cav going much beyond the first week (perhaps a little PR bidon carrying, leading the group up to the first climb, etc.) and then Sky can settle down to the business in hand.
Frankly, at the moment, he's proving an unwelcome distraction - not his fault, of course, the guy likes winning bike races (and there's nothing wrong with that). However, as many here and elsewhere have said, if he wasn't "Cav", and the World Champion to boot, Sky wouldn't have taken him to the Tour in the first place.
To be honest, Wiggins is so....."unusual", he might like the fact that all the talk is about his teammate and not him.
But, for all that, Cuddles has to love this, he's just got to love this - winning on points without a doubt - he probably sleeps with a smirk on his face....
