I agree with you that new players are not getting a chance in the team, PCB is adding the same old and old players to the team only because of influence of Pakistani selectors. Shaheen Shah Afridi has been a flop player for a long time, and as far as Shalab is concerned, his selection was not even in the team, but he has been made vice-captain of Pakistan T20 team. The Pakistan Cricket Board has become a very corrupt organization since Mohsin Naqvi took over the chairmanship of PCB. The Chairman of PCB, Mohsin, is a relative of the army chief, so he is only making selections based on his relationship, and they didn't improve basic instructions of Pakistan cricket. The thing to think about is that the head of Pakistan Cricket Board, Mohsin Naqvi, is holding three ministries, so how can he fix Pakistani cricket?
Mohsin Naqvi only qualification to hold key offices in Pakistan including the office of Chairman PCB is that he is Cousin of wife of Pakistan Army Chief. He has strong support of Army chief and as long current army chief Gen Asim Munir is in power no one can remove Mohsin Naqvis as Chairman PCB. If Chairman PCB is not selected on merit then how can he run matters of PCB on merit? I don't see improvement in Pakistan cricket team performance as long as Mohsin Naqvi is in power.
The senior players like Babar Azam, Shaheen have availed enough chances and they have proved with there performance that they are not worthy to be in team.
