Your idea is 100% true and everyone will agree with your idea. If the Indian team management had given importance to the team selection and chosen to bowl on the Ahmedabad pitch, they might not have performed so badly that day. Rahul Dravid's team selection was not wrong, but they should have considered the spin on the pitch that day. Only Virat Kohli, Rohit Sharma, and KL Rahul's contribution was noticeable that day but others contribution fully zero.
OP, I appreciate you 100%, but the Indian team management hadn't given importance to the pitch. If they had given their look on the pitch, they would have done anything before. Here we can't find that. They felt proud of the previous matches. They thought that the Indian team would be the winner that day naturally but unfortunately, they were defeated. They forget that it's a game of Cricket here that has occurred anything at any time.
