Man, how do all these skinny Pakistani guys generate so much pace. Sami is pretty quick (although he sucks) Aamer is supposedly 18 or something and hits 150s consistently, Wasim was a pretty thin bloke himself too. Only Shoaib and to an extent Waqar were solidly built.
We have guys like Zaheer, Irfan, and Munna who physically look like they can bowl quick, but end up topping out at like 135.
