That's strange. Because other people on this forum have argued the complete opposite. That Sky consistently winning (or nearly winning) stage races from February to July is also a sign of doping.
How can it be both?
Because Sky had multiple legitimate stage racing contenders. Break it down by assumed leaders at stage races and things look ridiculous.
-Froome and Porte appearing and destroying everyone, every time on a light schedule. It bears repeating this field destruction didn't occur at lower-ranked races.
-Wiggo doing well on a light schedule until the Giro
-The Colombians on a lighter schedule doing fantastic.
From Sky's site, Froome's HEAVY 2013 schedule:
11-16 February Tour of Oman Froome-dog destroys
6-12 March Tirreno - Adriatico Froome-dog destroys without Porte
--break--

2 - 9 June Criterium du Dauphine (Froome Porte return and destroy)
---long break---

15 September Montreal (Froome Porte joy-ride)

--cycling appearance fees holiday ends

25 September TT Monster Froome doesn't ride the ITT. Seems legit.
