Well the talent pool is India is humongous as you might atleast be aware of the players name after creating almost all of them in the Big Ant's cricket Academy for DBC, Ashes and now Cricket 19
.
The India A team is being managed by Dravid and has several A tours and a lot the players who does well in those tour gets picked on the national side in the recent. The likes Pant, Shankar, Shaw, Khaleel, Agarwal, Vihari, Gill, Shaw , Siraj etc. are some of the players who got picked because of their performances in these A tours.
The addition of Pant in test team was not on the fact that he is a very good dasher in the IPL but because of the fact he was doing well in the longer format in the Ranji Trophy as well the A tours same can be said about Agarwal , Vihari who made their test debut against Australia where they played a crucial role in helping India win the series against Australia.
I am expecting atleast 5-6 of the current roster (a year and a half) being replaced and the future lineup might loosely look like this.
Agarwal/Pritvi Shaw
Rohit
Kohli
Gill/Iyer/Rahul/Nitish Rana
Pant (WK))/Ishan Kishan
H Pandya
K Pandya/Sundar
Kuldeep
Chahal/Shreays Gopal/Markande
Khaleel/Deepak Chahar
Bhuvi
Shami/Siraj/Saini
The list can even go on and on and on..... We definitely do have the players in our ranks who can step up and definitely do better if given chances and are backed up and utilized by the management.
