Nothing is wrong with players being religious collectively. Islam is part of the culture of Pakistan so what do you expect? Religion is not something you just can just separate from collectives like they do in the West. At least they are not collectively going to night clubs and match fixing anymore.
A few months ago we were saying how Islam has transformed the team for the better. Rather this poor form has nothing to do with religion and, in my opinion, is entirely to do with injuries, poor selections and a poor batting order.
