PCB selecting unknown faces in the squad is not the problem. But not giving enough opportunities and dumping them after a single tour is the real issue here. There is no lack of talent in Pakistan. But the PCB has been notoriously incompetent in grooming this talent.
It goes without saying that the new players that the PCB has given a chance to are extremely talented, but the PCB could never have imagined that they would perform so incredibly poorly in the first T20 match of the New Zealand series. The new players who have been given the opportunity have mainly performed very well as native Pakistani players in the Pakistan Super League, which is why they have been given the opportunity so that they can perform well and create a balance in the team. However, I hope that Pakistan will definitely correct the mistakes of their first match and perform much better in the upcoming second T20I match.
