Nah that Hauritz talk is a myth. Yea Ponting encouraged him to be aggressive in interviews etc. But quite clearly Hauritz bowled no different in IND 2010 that how he bowled since he was recalled for the MCG test 2008/09. The Indian batsmen just smoked him accordingly & better than what international batsmen where doing (should have been doing for 2 years). Im sure you have all people will recall how the Indian batsmen was just the way Ross Taylor had crashed in a test in NZ in early 2010.
There is no question he bowled different in that series compared to how he usually bowled. He was bowling a more attack line which is not in his natural game.
Ok & what gives you impression that Smith doesn't have the confidence of Smith?. When you see articles this this:
Steve Smith hailed as new Steve Waugh | Herald Sun
Which highlight the fact that Ponting has had private convo with Smith about his importance to the national side (although i feel in some ways his importance is being over-rated), that is clear sign of confidence for eg.
Plus i definately i have seen no evidence that Smith looked more comfortable while Clarke was captaining him in AUS, compared to when Punter is in charge - none whatsoever.
Talk is cheap action speak louder than words. If Ponting was confident in Smith he would have used him against Pakistan.
Compare how he has bowled this WC to when we played against England. It's obvious where he looked more comfortable and the stats reflect it.
