Who else would you have if not Mush? His basically the last of the thinking players...we have already had mortaza n shakib.
We cant blame him for our bowlers being rubbish really. Pak bowlers couldn't do much bowling 1st so what would our bowlers have done??
Plus I dont think he alone makes the decison whether to bowl or bat. The couching staff must also contribute so I do not think you can blame him alone.
