Woot, my two favourite subjects, height and speed.
Despite the talk about Pakistanis being better "built" for fast bowling, a lot of them are really very small for fast bowlers. Akhtar is 5'11", for example, and there are a number of others of similar stature- I don't think Riaz or Ahmed are much taller, and Umar Gul looks tall by comparison but is really only 6'1"- 6'2", and about 3 foot of that is his head.
Mark Richardson was interviewing Waqar Younis the other day and I was a little taken aback that they are basically the same height, so about 5'10"ish. I know he isn't a fast bowler, but Shahid Afridi is nevertheless built like an archetypal strong Pakistani cricketer, yet he is clearly shorter than Ross Taylor, so again, no more than 5'11". I daresay Rana Naved and Razzaq are similar and Sami a bit shorter.
It's funny because in the last 20 years I can only think of Danny Morrison and Andre Adams as NZ pacers of similar stature, yet Pakistan have a production line of blokes who can nudge up to 140kph or higher. I know height is useful, but are NZ missing a trick somewhere with the relentless 6'3" and over 130kph bowlers? You can't really say Pakistanis are built for pace bowling in the conventional sense as by international standards a lot of their quicks are tiny.
