Re:
Basically there are two Sky's:
The first one burst onto the scene in the home olympic year 2012 when they found themselves in a situation were zig-zaggers and trackriders had evolved into GT-winners and olympic medallists. During this period when Wiggins was the top dog they had to keep climbers or lone wolfs caged to keep control of procedures and not taking any risks. Therefore the strategy with making every dom a possible GT-prospect delivering a 450W-guarantee over the course of three weeks. This is whats needed to be done in order to avoid actual tactical situations and gain knighthood.
Secondly: the rise of Froome. Ever since the great discovery of the kenyan, and that he was willing to go the distance and develop beyond being a pure TT-rider and phantom climber, they figured in the tool box of Dawg was also a hill specialist and Paris Roubaix-strong man in the making. The perfect Tourminator who just had to stare on his stem for things to happen, and once again mask the tactical shortcomings. This has of course lessen the burden of superdoms. You simply have to had the rider to whom the law of physics no longer applies, who can pull back attacks on his own, go on breaks, soloing on cobbles, pull back breaks, sprinting with hill specialists while still have reserved wattages for crushing time trials and seated sprint attacks over cols with favourable tailwinds and 15% technology bonus.
I say yes they are tactically inept. But its not like they need tactics either.
