Pandaya will never be good enough to fill in the second pacer spot because his job is to control the flow in the middle overs and he is being excellent in this format but with new ball I doubt he can make any impact at all. I am trying to say they have to build the confidence among the group as soon as possible. The should have played Shami in the place of Nithish Reddy who didn't contribute much because the situation didn't needed an extra bowler nor the batter at deep.
I do agree that Pandya is not good enough to fill the space for the second pacer. But, remember we still have Bhumrah, Shiraz, and a few new guys who can fill the second spot. It is just that India has a lot of talent pool and someone from that pool will be part of the team as backup next year in the WC. I still did not understand why Nitish Reddy did not get an opportunity to bowl yesterday, he could have been used to replace Hardik but he was not. The captain and the coach are more aware of the condition and accordingly, they make the choice.
