Re: the sky riders in a breakaway point, over pretty much the entirety of the last two tours they've been defending the yellow jersey so have had their hand forced into the defensive style of riding we see. Two years ago when Brad crashed out they got a lot more involved, and I'm sure they would again if they didn't have a rider in contention. Most teams with riders in the breaks never have any real GC ambitions or have lost them during the race hence the ability to free them up to go galavanting for a day.
I was talking about Sky as a team, you seem to be talking about Sky performance with regards to the Tour de France specifically.
Team Sky have never been in real contention for a classics victory, in fact in the 2013 Paris-Roubaix results no Sky rider featured in the top ten, did they ride more aggressively as a team, nope... did they send a single rider up the road, trying his luck and taking a roll of the dice.. nope. .. So even when they are not in contention, they do no real galavanting of note
Likewise in the Giro they supported Wiggo blindly for far longer than they should have, it was obvious to most people that he was not in form, long before he withdrew. If Sky changed tactics earlier to support Robert Urban they could have won it.
They make a plan and follow it, that's why they lost the Giro.. That's why I doubt you will never see an incredible ride like Tom Boonens solo break away for 53km in the 2012 Paris Roubaix from a Team Sky rider as they have to calculate the best odds by which time the break away or opportunity has passed them by ... As previously stated they are effective, calculating and the results speak for themselves but my god are they booooring to watch.
Its all about OPQS baby
... the Manx missile, TT King Tony Martin, Boonen and the fiesty Chavanel ........ Riders with heart, entertaining and exciting to watch suffer.
