Sky probably are better managed than (most) other teams thanks to their resources and budget, and having a better sense of team than other big money teams like, say, BMC. The other examples that could be pointed to are OPQS and Katyusha, with budgets and success but highly suspect people on board, but are being beaten by Sky.
The problem is, to believe that such sharp, almost unprecedented (only really precedented in cases that have all ended the same, negative way) improvements are entirely due to Sky's better resources and man management would then imply that, as they - often even with doping programs - are being left behind by the sharp improvements of the slicker, more professional Sky riders, almost every other team is managed by Dupont and Dupond. Much as I am happy to believe that the bilharzia existed/exists for Froome and explains much of his time as pack-filler, but am highly suspicious of its convenient timing and how insanely instant his transformation from looking-at-a-possible-domestique-gig-for-next-year to making-Contador-look-a-fool was (especially given that the bilharzia essentially makes his BP worthless as no real baseline can have existed because of the effect on his blood values of the disease), I am happy to believe that the Sky team gets some benefit from being organised better and having more resources than most of its competitors, but I am also unwilling to conclude that the improvements in resources and organisation alone can account for the sudden, marked and quite dramatic improvements shown by a number of key Sky riders. The presences of guys like Leinders, Yates and Rogers did not help, even though they're now gone.
