I agree. The Shack and Sky will struggle to win anything. Take the Shack, mostly Astana's A-Team, who collectively struggled to win anything. Yeah Levi won in California and the algarve and a few ITTs, Brajkovic is quality for the stage wins and classics, but the team is sadly geared towards pulling the old man on the roster around France. Astana achieved more victories overall and stages via Contador than the rest combined. Good move Lance and Bruyneel.
As for Sky, yeah they might win a stage or two in the grand tours with EBH and Gerrans but thats it. Despite this (no shame there as the chances to win are few and far between) they will actually have a crack at the classics and week long races. They won't be up there with with Columbia, Saxo, Caisse, Rabo, Liquigas and Katusha in volume of wins, though this won't matter, they will easily double the Shacks number of victories. Sadly the muppets at Radioshack are bank rolling the vanity of one man in the pursuit of one race. Then they'll depart the sport, like Postal and Disco. Everything else will be a minor inconvenience, except California, which will be used to help convince Levi to put his aspirations aside and pull Lance around the Alps and Pyrenees in July.
Sky are the better team, but the Shack will get the media's attention, particularly in America, even over other US teams like Garmin and Columbia. Personally I think it stinks, but the inevitability of the situation is glaringly obvious.
