Squad for Nagpur Test: Mahendra Singh Dhoni (c), Virender Sehwag, Gautam Gambhir, Sachin Tendulkar, Virat Kohli, Cheteshwar Pujara, Ravindra Jadeja, R Ashwin, Piyush Chawla, Ishant Sharma, Ajinkya Rahane, Ashok Dinda, M Vijay, Parvinder Awana.
So taking squad for Final test as starting point, i would drop -
Sehwag for poor form
Gambhir for poor form
Chawla for being **** and undeserved selection anyway.
Dinda for same reason as Chawla.
Ishant for being poor for a while and not still knowing how to get test wickets.
Vijay for same as Dinda and Chawla (though less ****).
Sachin won't be dropped and Dhoni won't either probably as he seems likely to remain as Captain with only other option being Kohli.
So Changes for me keeping that in mind would look like -
Abhinav Mukund (in for Virendra Sehwag)
Unmukt Chand/Jiwanjot Singh (In for Vijay)
Wasim Jaffer (In for Gautam Gambhir)
Umesh Yadav for Chawla (If not fit then Sidarth Kaul/Ishwar Pandey/Bhuvneshwar/Mohit/Warrier comes in)
Pankaj Singh for Dinda
Shami Ahmed for Ishant
Which makes the 14 man squad look something like this -
Mahendra Singh Dhoni (c), Abhinav Mukund, Jiwanjot/Unmukt, Sachin Tendulkar, Virat Kohli, Cheteshwar Pujara, Ravindra Jadeja, R Ashwin, Umesh Yadav, Shami Ahmed, Ajinkya Rahane, Pankaj Singh, Wasim Jaffer, Rohit Sharma
Awana unlucky to be cut for squad balance's sake, but he was lucky to get the call up in front of other options anyway. Also, i'd personally remove Dhoni from the Captaincy and make Kohli captain but that seems unlikely, so he stays in the team. Otherwise if he is to be dropped then Saha or Gautam come in.
Edit - Ashwin should be in the last chance saloon after the first test too with Rasool/Nadeem/Ladda being potential replacements. And Jadeja should not play as a all rounder at 6/7.
