It is very close between young Amir and Shaheen, but Shaheen has the added advantage of his height which he hasn’t exploited yet.
If Shaheen can learn to use his height, he can easily become the best fast bowler in the world. He has all the qualities.
As far as retiring from T20s is concerned, I think it is too early for that. He is at a stage where he needs to bowl as much as he can and play all the formats.
His workload should be managed of course, but in my opinion, he needs to play all formats.
The part about height is correct: for someone who's about 6 ft 5, he hardly knows how to generate variable bounce for certain situations.
When I see Shaheen Shah Afridi right now, I see someone who's potentially got more skills than anyone Pakistan has produced at that respective age.
But I also see someone who isn't harnessing his full potential, mostly due to the inadequate and incompetent coaches he has had in his coaching career.
A team like India or England with Shaheen would have made him into the world's greatest bowler across all formats by now.
Tall bowlers throughout history, especially tall express fast bowlers, have had brutal bouncers. Whenever Shaheen bowls a bouncer, it looks so easy to negotiate.
Furthermore, once the ball stops swinging, I think that he really struggles against players who are strong on the back-foot, guys who can cut the marginally short ball or pull him on the front-foot on a short-pitched delivery.
His slower-ball is also not that effective, because it's not that difficult to spot, and he doesn't always have the best field set for it.
I do believe that under proper coaching and guidance, Shaheen would have reached 100 test wickets already, and would probably be around 70 ODI wickets and 45 T20I wickets.
It's a shame that the PCB has been so poor with managing and developing such a wonderful talent, a generational talent that is.
I can understand playing all formats, but I have my doubts over PCB's ability to manage his workload. There's a reason people from vastly more professional setups keep stressing the importance of managing Shaheen Afridi with great care. If only our incompetent and inept board heeds the subtle warnings these wise people give.
