Bumrah, Arshdeep, Deepak Chahar and Nattu with Jadeja, Axar and Hardik as all-rounders is a good line-up. All the oldies in the T20 team should go away and play ODI and tests alone. Bhuvi, Shami, Rohit, Rahul, Ashwin, Dinesh Karthik should all be dropped.
Shaw and Pant opening for India will be a dream. Kohli at 3, SKY at 4 and Hardik at 5 is solid. Should groom and select one player between Hooda, Tilak Verma , Rana, Tripathi or any under-19 guy for the number 6 position. Criteria should be to be able to hit from ball one and also bowl a couple of overs. Need just a 10 ball 20 from one of them.
Jadeja, Axar and Chahar from 7-9 can be the backbone for the batsmen at the top to aggressively get going from the start. Bumrah, Arse/Nattu to complete the line-up.
