I believe that was against NZ. Shakib was set and start slogging in the later part of the game and got out. The commentator was saying (before he got out) "why not using batting power play now, if you plan to slog?". thats was so valid, that would give Shakib more success of survival when hitting aerial shots. And then during the 45-50 overs, with wicket on hand, you can always slog... with or without batting power play.
So, yes, I agree, we still didn't mastered to use the batting power play to our advantage and integrate with our batting game plan.
