I'd like to think he's saving his energy, i.e. if he's not going to win, theres no point in tiring yourself out. Looking forward to seeing him bawling his eyes out later on in the tour.
He is probably suffering a bit from not having Eisel with him this year.
He always used to take a few stages to get going, even in his pomp.
I thought Gaviria would take his mantle at some point, it looks like that time is now.
