Well we all know his talent was never quite realized, he lacked focus and dedication required away from matches to perfect ones skills, but in terms of raw talent, where does he really rank?
Mohammad Zahid, who at his peak was quicker than Shoaib and also bowled an unplayable over to Lara, getting him to miss 5 deliveries and dismissing him on the 6th, had the following to say:
PakPassion.Net: We've all heard the stories of Inzamam thrashing Waqar and Wasim in the nets, when they were both at their prime. How did Inzi handle Zahid in his prime?
Mohammad Zahid: Inzamam is a different story altogether, he was always too good. I never saw him impressed with what I did, it didnt matter how fast I was bowling to him he just wasn't bothered by it. It didn't matter if I was bowling to him in the nets or in a match, the result was the same. It used to amaze me that even when I was bowling at full tilt and holding nothing back, Inzi would still be playing me quite comfortably. I've never seen another batsman who has so much time when playing the ball.
Also, Shoaib himself asserted in an interview that he never even came close to troubling Inzamam in the nets or domestic cricket, despite their much publicized differences. That inzi seemed to have a ridiculous amount of time to play pace bowling.
I also recall a practice game against some Australian side when Brett Lee was in his prime, Lee was charging in at full pace, and it literally felt like Inzamam was playing a medium pacer. I think Lee ran right upto him at one point, and Inzamam jokingly told him to stop bowling off spin.
It is also interesting to note that Lara also told Zahid after that famous over that he was the quickest bowler he had ever faced.
