Lol! Talk about jumping the gun and that is what many posters are doing on this thread.
No one mentions which players should have been selected with a reasonable and factual basis rather everyone starts to criticize the players being selected.
Other than 2,3 names on top of my head I cant think of anybody good enough at the moment which could have been considered other than the players already selected.
Which extraordinary opener is missing? We need to accept the fact that Fakhar, Imam, Shehzad, Shan, Sami Aslam, Abid Ali are the best ones we have at the moment (Only 3 could have been picked). Talking about Zeeshan Malik, Sahibzada Farhan without them performing in even two consecutive seasons is not how a squad is selected.
Also which exceptional talent are we missing in middle order? Babar, Haris and Sarfaraz are enough to play innings builder and consolidation role. Talking about Saud Shakeel, Saad Ali etc is again useless exercise as a LOI team requires attacking batsmen along with consolidators. Playing Saad Ali and Saud Shakeel at no 6, 7 is gonnna result in same way it resulted in Aus series for Saad Ali.
Which are the best aggressive middle order batsmen we have in Pakistan? Again a bitter truth which many wont like that they are Umar Akmal, Iftikhar Ahmed, Asif Ali, Khushdil Shah and to push further Sohail Akhtar (Not suitable for ODIs in my opinion) and Adil Amin. 3 of which have been selected in probables.
Now coming to pacers, which one is exactly missing? Talking about Musa, Haris Rauf, Naseem Shah when they are yet to play few domestic matches is again not sensible. Its arguable the spot Hasnain got early this year for a young fast pacer could have gone to Haris Rauf as well but now you cant have 3,4 pacers with almost no FC experience representing Pak in national team. Let the others play a bit to understand their own game.
In spin department I agree that there could have been one more specialist spinner but then team management has thought about going with one in Shadab and 3 options in Imad, Nawaz and Iftikhar in probables. Still would have liked to see one more specialist spinner in the probables atleast.
So I personally dont know which exceptional players are missing from the probables.
