Man your understanding is so lacking. In ODIs facing seamers with a new ball is so different than coming in the 20th over facing slower bowlers and with a semi old ball. And also as a middle order player your mentality is to face spinners and slower bowlers. Everythings so different. No wonder the Aussie team never does this kind of experimentation. Thye never told Langer to play at no 6, he alwyas played no 1. I ask if the best team in the world doesnt do it why India has to do it and be successfull too. Jayasuriya Saeed Anwar etc etc are the great examples of how sensible those boards and the coaches were in not meddling with your star batsmans position. Please dont argue based on myopic views like this.
