That's a pretty simplistic view of Grand Tour stage racing.
A possible podium sweep would have been a secondary effect of playing that stage as Johann wanted, not the primary.
The worker bees couldn't possibly get AC higher up in GC. He was leading!
Once Wiggins had been dropped all AC had to do was mark Schleck. He already had 2:30 on him. The attack created unnecessary risk. The Schlecks loved it.
If the Schlecks had attacked the end and AC covered it would have had the same result. But if he'd have given Kloden a moment or 2 he could have had help instead of being isolated. Kloden not losing time or Lance bridging up would have just been icing on the cake.
Just because it worked out doesn't mean it wasn't a dumb move.
