Tigers_eye: Rarely disagree with you, actually never, other than this one. Given the realities on the ground, if Naem comes in, that should be the time we take the power play given Riad/Mushfique is with him. There is no point in waiting for Razzaque/Shafiul/Rubel because they dont even know how to swing the bat... forget baseballing!! Hence, I think our strategy should be based on wickets than which over we are in... If we wait till the 40th over when 7 wickets are down and the bowlers are in... taking or not taking powerplay is absolutely meaningless.
Another innovative approach would be to take the batting powerplay with Tamim/Mushfique/Riad combination. They can find the gaps and take advantage of the fielding restrictions.. So we keep the momentum with the openers or when we are on a roll. Yes, there is always a danger of loosing the wickets and if we do lose them,, then we just bat as if we are not in batting power-play.
Bangladesh is one of the worst offenders when it comes to batting powerplay.. because our captain(s) tend to go with what other teams has done based on their strenghts than the realities of BD cricket. We try to follow a scripted approach on few things; like having pacers bowl during dead overs, have defensive feild settings during mid overs etc. And for batting power play,, we definitely need to rethink than thinking the traditional way of things that dont work in this era..
