It is better to keep the same team and the positions. If Rahul and Jaiswal could buld a 201 partnership, let them come as no 1 and no 2. Let Rohit come as No 3. Keep the victorious team intact.
In T20 also, let Samson and Abhishek come as No 1 and No 2, with Tilak Varma at No 3. Surya at No 4 et al.
One huge problem we foresee is the Pink Ball which will swing and spin more. There was no need to introduce the pink ball at this stage. Yesterday, Pujara was giving tips to Indian batsmen how to negotiate the pink ball. The Indian team must have started practice against the pink ball. Thank God we have 8 days to prepare.
