Interesting choice of words. Remember he was the only one who stood up in England when all around him were betraying him? He like anyone else is allowed a few failures.
Honestly don't look at the small picture. The results matter, but the rebuilding matters a lot more. We had a mega generation playing. Sadly the rebuilding process has come during the phase of the four toughest tours there are in Cricket for an Asian side. However look how far we have come from last year in SA, when we had no openers to speak of, no middle order, and we didn't know how Pujara, Kohli and Rahane would perform, whether they would perform. We had a whole batting line up to find, and 1 year later we are nearly there. Thats good rebuilding effort.
The results will come. A few more pieces to go, especially bowling. Patience, rebuilding is not done at the drop of a hat.
