How do you suggest he defends without working on the front? Contador won it in 2010 by reacting to Andy's attacks and sealing it in the ITT. Wiggins would have never been able to pull that off that first part, even with climbers less skilled as Andy. We actually saw that happen. Without Froome pulling him back, who knows what would have happened and how much time he would have lost. He would also have been more tired by the time the final ITT arrived.
Because he was the MJ, then state of things absolutely suited him and he could ride how he wants. The main problem is to arrange proper carnage strong teams are needed (we had no them by Sky, and we would have had no them without Sky. It could have been a lame team powerlessness). Strong climbers are often not enough. In addition to gain a lot of time strong climbers must work together and overly consensually which is hard to assume 'cos very likely they ride in different teams. I absolutely sure even Schleck and Contador, working together, are not able to give 3-4 Tourmalet during a GT, because no matter how one would like to overrate ones and belittle others, the contention among 5-6 best climbers when they are on form is VERY tight. The 2011 Giro and the 2012 Tour were rather exceptions in this regard.

How about tiredness of hypothetical attackers, ah?

IMO, to attack is much more energy-intensive than to sit behind Wiggins, isn't it?
You reason like if strong climbers offered an intensive torn tempo with lot of attacks, it would have demoralized Wiggins and he would have given up. It is not so. I think he could quietly have sat behind other climbers. He could sit probably behind all but Nibali and VdB sometimes. If like of Pinot had tried something, Wiggins even wouldn't have budged.
