I don't think it is reasonable to announce a T20 series by excluding players like Babar Azam, Naseem Shah, Rizwan from the T20 format because such experienced players should definitely be included and some new players should be given a place in the team, otherwise if a series is conducted with completely new players, there will be a lack of good leadership in that series. There will be bad performances on the field of play sometimes, but wrong decisions cannot be made later by taking that performance as serious.
PCB is probably very dismay with Babar, Rizwan and Naseem Shah. These three are the most experienced players in the pakistan squad. But we have not seen good performance from them for a long time. The Pakistan board has given a lot of time and opportunities to babar and rizwan. But even then the performance of these two players is still weak. That is why the Pakistan board has sent these three players to take a rest. However , I would say that this rest should have been sent earlier. Even if they were not kept in the squad for the Tri- series, experienced players like Babar, Rizwan and Naseem Shah were needed in the squad for the Asia Cup.
I think prime time of Babar has gone because every player has up and down but he should take rest and should work on the performance and he has capability to come back to the team . Selectors dropped these players because they got alternatives of these 3 players and I think Haris Rauf should be off from that team because he is not giving credit to tge team because he is not quality bowler and not tough bowler at the end.Rizwan era has gone because we saw that he has few shorts and at that time , his existence is very difficult because he has to change his performance to be part of Pakistan team.Naseem Shah is useless bowler and he always try to make position in the team but Pak team need new talent to win the match.
