I am with you. The main reason I think the sponsors who are patronized by financially strong groups of business tycoons who in a large extent are huge fans of Pak cricket for a long time. Their enthusiasm to watch Pak players with the huge market interest from a good number of female fans make this more favorable to play as many Pak players possible.
Aside from that you can add the political views of such people as a minor ingredient to instill the passion. With all that said, you are quiet right about choosing players from different teams and the payment factor.
Life is short, have a six pack.
