Based on your analogy Amir should have been the same bowler that he was when he got banned. Except he wasn't. He was a shadow of his former self. And so is Sharjeel. I doubt he can even play a full ODI match based on his level of fitness.
LOL attributing Fakhar to PSL is quite a stretch. McCullum may have played a part in grooming him or giving him chances but Fakhar's breakout PSL season was an abysmal one in which he scored one fifty. Fakhar got identified through his performances in the 2016 and 2017 Pakistan Cup, which also led to selection in the Champions Trophy squad. Without that 2016 season there might never have been a spot in the PSL and without the 2017 season there might not have been a place in the CT squad.
Asif Ali was selected for Pakistan based on his performances in the PSL in which he played an important role in winning the trophy for IU. He had a very good season ending up with a SR of 169. So maybe you should go and look at the stats.
Really? Surely a player with 'talent' should show some flashes of their talent even if he hasn't developed as a player. So what flashes of talent has Talat shown based on the chances he has gotten? If he hasn't shown anything by the age of 25 despite playing 20 odd games for Pakistan, many of them against Zimbabwe, second string West Indies and second string Sri Lanka; than chances are he might not be setting the world alight anytime soon.
Khushdil may have gotten lesser chances so I'm willing to reserve my judgment on him. But thus far he has been an epic failure, despite being one of the most talked-about PSL products.
Sharjeel was for T20s not ODIs yet.
PSL obviously doesn’t produce the player, it just highlights them. If Pakistan Cup and QEA performances were being rewarded for Pakistan call-ups, we would not be the mess we are today and the likes of Rizwan, Hassan Mohsin, Fawad Alam, Usman Salahuddin, Saud Shakeel etc would have played many more games for Pakistan by now. Let’s be real.
Fakhar got noticed and selected because of PSL during a 33-ball 56 against Karachi where he destroyed the opposition bowling and looked extremely elegant while doing so.
Before the Champions Trophy, It earned him a call-up to Pakistan’s T20I side for the West Indies tour, and he made his debut in the second match in Port of Spain.
His first three T20Is only brought him 26 runs!!!
The ODI debut came months later. Khuda ka shukar Fakhar wasn’t dropped after 3 innings as was the case with Talat recently.
Asif Ali has fulfilled his low potential. He was always overrated based on one PSL season.
List A: 30 average at 115 SR
ODI: 26 Average at 121 SR
Fulfilled his low potential..
Domestic T20: 18 average at 134 SR
International T20: 17 average at 124 SR
Fulfilled his low potential...
Khusdhil and Talat must get a long-run in ODI and T20s before they can be judged.
