The one thing you can be certain of with Pakistan is that they will inevitably surprise you with their performances on the field. They are currently playing an ODI series vs Sri Lanka and have maintained a strong Castrol Index of 151 points. With the ICC World Twenty20 looming, in Sri Lanka, they are sending out a very strong statement with their bowling.
I don't know if there is a sporting DNA but Pakistan seems to produce bowlers with far greater regularity than they do batsmen. If you ever have a choice between one or the other, you'd always want to have bowlers on your side because they tend to win you more matches. And just looking at this Pakistani bowling line-up, it is difficult to believe that in the last eighteen months they have lost three match-winning new ball bowlers.
Currently, Pakistan can call on Sohail Tanvir, Umar Gul and Mohammad Sami in the fast bowling department and I am absolutely certain there are five others either waiting to be discovered or returning to form. As a result, they can play around with whoever is available without losing too much potency. And since continuity has rarely been a strong point with them (almost all their bowlers go through form swings faster than a prima donna does her moods!), they just move on without losing too much sleep.
