I agree a lot with this . Blame is on both sides - Young players not showing consistent performances or not playing , and selectors not taking bold decisions by picking young players in place old pacers who are past their prime.
1. If a potential India pacer does not play many matches in domestic due to injury
2. If he is not able to give consistent performances whenever he plays in domestic
3. Cannot even get a place in state team (though in some cases it is due to biased selection) ,
how a selector can play them in India national team ?
The most, India A team selection can do, is to play these in A matches if state teams do not provide the opportunities & assess them .
In this respect Akashdeep selection is justified at this moment , though he may also struggle to take wickets in these pitches.
