That's how we roll in BD. One day spinners failed so we used all pacers next game. One day bowling first failed so we batted first the next. Trial and error disregarding logic.
With BD batters' lack of temperament and ability to pace their innngs, they should always bat second and chase down a target against stronger oppositions, at least in T20.
In Darwin's eyes, Bangladeshi batsmen are still monkeys with cricket bats.
