PCB is a terribly run organisation on that I will agree with you. But as a fan I am like the BCCI, I make exceptions for ICC World cup competitions, for those we need to pick the best team to perform at the time, and the preparation should start now. If Usman wants to be part of it then he should be. If he wants to represent UAE for an easy life no problem, that is his right as well. Just move on and pick someone else.
Apologies if this post is long to read:-
The BCCI is one of the most competent boards out their, 2nd only to Australia when it comes to developing players.
It isn't a coincidence that sehwag, Sachin, yuvi, Harbajan get replaced by talents such as kohli, Gill, rohit, Chinaman etc etc
First of BCCI has literally selected a pool of 30 players, They have an entire string of players ready to replace their legends once they retire.
Secondly they don't abandon their players or treat them harshly or even punish them. Sanju Sampson was extremely upset he xpuldnt make the squad for world cul, but bcci assured him that he'll be fine, kohli and the others even appointed him a proper Coach to iron out his abilities and make him better.
Rohit went from being am average middle order bat to one of the worlds finest openers to ever play the game, Rahul went from failed opener to clutch middle order bat, Dhoni in his first few games failed and was worried he'll be booted out of the team, instead they just reassured him and had Dhoni meet up with his local coach, after ironing out some issues and a few months of work he became their greatest finisher ever and greatest captain.
Bcci knows how to develop players, someone like rohit and Dhoni don't just drop from the sky for them lol.
If saim ayub was playing for BCCI, he'd basically be scoring 200's and be a generational superstar for them, since they'd assign him the perfect coach and in IPL and domestic they'd prepare tough pitches for him and tough bowlers so that he is brought up to international standards, Mainly because they recognise that for a 20 year old he's technically sound and is brave enough to develop unorthodox shots, he'd be eye candy for bcci.
But in Pakistan saim is likely just gonna be an average explosive opener.
Pcb is not bcci, Usman Khan isn't gonna change the game because our board has no clue how to groom players.
This board is so stupid that it doesn't bother to improve someone like fakhar zaman, instead loses confidence in him and shoves him to no 4, even though fakhar has won tournaments, played innings babar can only dream of and is the only player who can hit mighty 150 scores for Pakistan at a very high strike rate.
This board has delusional held babar and the way he plays as the Pakistan way and him being the source of inspiration. Babar wouldn't make it to the Indian 11, same way he went unsold in the 100, No one is interested in a coward batsmen.
Imagine pcb thinking babar is no 1 when dozens and dozens of batsmen outperform him in cups every single time, Warner, Maxwell, Kohli, Quinton etc etc.
Usman Khan is playing under the wrong board.
This isn't bcci, it's pcb, massive difference.
