Look at India, they have SKY, Rohit and Rahul at the top, then comes Pant, then Pandaya, then Jadega and Kartik, they do not stop hitting at any point whereas our so called hitters cannot even hit few boundaries on Pakistani pitches, what will they do in Australia.
My opinion would be to include all youngsters, right from openers till number 7 with only Babar and Rizwan mixed in the middle. Only one of the two should be opening, the other one should only then come when first one is out. With our mindset and system, there seems to be another 100 years that we come to the same scale as India, England, South Africa etc are. Even Sri Lanka has understood the format now and are looking in great shape now. We are 90 % dependent on our bowling and rest on Rizwan's gutsy batting. With this we can win odd matches in between but will never win tournaments or series against good teams/bowlings.
