Thakur isnt good enough for any team. His only utility is on green pitches or swinging conditions as a 4th choice test pacer. That's it.
Why Thakur? Players like Mohsin Khan are sitting at home. While this guy is playing. He doesn't bat well.
Axar should not be playing, his bowling in LoIs is down right average. Rahul Tewatia is a much better option. And if we are playing 2 ARs like Hardik and Jadeja, Hooda is a better option for replacing Jadeja. But they wont play.
Again Chahar is not an option. How many swing bowlers you need? BK, Arshdeep. How many?
Again the same bits and pieces argument of he can bat a bit. So? Are we going to replace a genuinely good bowler by a avg bowler who can bat?
Rahul Dravid is keeping genuinely good specialists out and playing bits and pieces players. And ofcourse the selection committee is very compliant to the wishes of a cricketing giant.
Again, all the names you quoted are backup options. How many of these guys played today's game? Thakur, Axar and Chahar none of them played today's game.
D Chahar will only play when Bhuvi is injured or rested and Bhuvi won't be rested as he only play T20s.
Thakur has not been picked for T20s in recent times. I agree he is not good for this format. Axar was only picked because Jadeja, Kuldeep and Sundar were injured. Jadeja gets free run because he goes off radar and fans like to target the superior all rounder in Indian LOI team, Pandya more
Have you not seen some of your specialists how they play, the bubble has burst for them too. Avesh, a specialist bowler has been bowling pies in all the chances he got. Prasidh is again not a T20 bowler and neither was Shami. Mohsin is still unproven, he had success only for half of IPL.
<B>In T20s, the best options are Bumrah, Bhuvi, Arshdeep, Harshal( yet to be proven overseas) and Deepak Chahar</B>. The likes of Avesh, Prasidh are not good enough in this format.
In ODIs vs England, we did picked the specialists. Bumrah , Shami, Prasidh/Siraj, Yuzi played. That's specialist attack. But in T20s, Shami and Prasidh are not good enough.
