Hindsight is 20/20. It was a sensible move at the time. Froome had nothing in his career before this Vuelta to indicate that he could podium, let alone win. Wiggins did. Wiggins is also still in a position to podium in a Grand Tour. Calling him "the great pretender" is ridiculous.
Froome has burst on the scene as a grand tour rider in this Vuelta. How many people were predicting that one? Good for him!
Hindsight? They had a pretty good idea of the riders' form after the TT. That's not hindsight. Sky/Wigans maintained the misguided stance of Wigans being leader and getting support in the face of that reality.
They maintained it in the face of reality on the lower slopes of the Angliru. Wigans knew he wasn't at Froome's level, one quick flick of the elbow or a quick selfless chat on the radio is all it would have taken, instead he tied his great pretender's boat anchor to Froome. No hindsight needed.
Dauphine? BFD. 3rd place in this Vuelta? BFD. This is as much as he will ever achieve, the hype that he would ever win a GT was just that. Assuming he would ever do better is what is ridiculous. Vaughters is laughing at the $$$ he fooled Sky into wasting.
Here's hoping Wigans wakes up and realizes his track skills are better served keeping the pace high in Cav's leadout.
