Because he did his job, in the last 11 matches that he has played, he has scored over 50 with a strike rate of 82.48..his only failure against Vaas, when Murli took a great catch.....Dada did not throw his wicket away.Dada was undone by a great catch.....compare him to others, using the Dravid/Chappell mantra of consistency and performance. India lost as they could not defend 191 against Bangladesh, due to Rahul being unable to bring in the spinners early and in TANDEM. Against SLanka, due to Shewag,Tendulkar,Dhonee,Dravid,Yuvraj doing batting suicide. Dravid scored but he was scoring because he was playing in suicide mode as there were no batsmen left...in normal circumstances he would have scored a 14 or a 18 in 40balls and would have been lbw...like he played 28 balls for 14 against Bangladesh and padded astright innocuous ball.
