In Australia India need 4 regular Pacers + hardik and 2 spinner will be sufficient
Bhuvi & bumrah is the must
And 2 from Shami/shardul/harshal/chahar/arshdeep
In spin department jadeja is the must
And one from bisnoi/Ashwin/chahal/kuldeep.
But that will make it 7 and with one wicket keep 8 ,
two openers
so only one batsmen in the middle order?
The problem is none of the Indian bowlers can bat and T 20 requires more all-rounder or bowler who can bat a bit and batsmen who can bowl. Even in ODI. Remember Sachin was a go to bowler, and match against S, Africa ad even the world cup India won (ODI) Kohli has bowled. Even rohit used to bowl but now all of them are pure batsmen and a bowler has to bowl only 4 overs . so 6th bowler is required if one bowler fails. so it has to be 3 pace , 1 spin a pace all-rounder and one spin all-rounder. Yes they will have to select four pacer in the team but in the final 11, it should be 3 pace, one spin and two all-rounder. More than that batting balance will be an issue. They may open with Pant or SKY , creating a slot for DK in the middle and dropping KL.
